bf4e7080ae fix directory locking scheme on rename 
broken in 6.5; we really can't lock two unrelated directories
 without holding ->s_vfs_rename_mutex first and in case of
 same-parent rename of a subdirectory 6.5 ends up doing just
 that.

5b9b41617b Another moderately busy cycle for documentation, including: 
- The minimum Sphinx requirement has been raised to 2.4.4, following a
   warning that was added in 6.2.
 
 - Some reworking of the Documentation/process front page to, hopefully,
   make it more useful.
 
 - Various kernel-doc tweaks to, for example, make it deal properly with
   __counted_by annotations.
 
 - We have also restored a warning for documentation of nonexistent
   structure members that disappeared a while back.  That had the delightful
   consequence of adding some 600 warnings to the docs build.  A sustained
   effort by Randy, Vegard, and myself has addressed almost all of those,
   bringing the documentation back into sync with the code.  The fixes are
   going through the appropriate maintainer trees.
 
 - Various improvements to the HTML rendered docs, including automatic links
   to Git revisions and a nice new pulldown to make translations easy to
   access.
 
 - Speaking of translations, more of those for Spanish and Chinese.
 
 ...plus the usual stream of documentation updates and typo fixes.

b6964fe239 Rust changes for v6.8 
Another routine one in terms of features. In terms of lines, this time
 the 'alloc' version upgrade is less prominent, given that it was fairly
 small (and we did not have two upgrades).
 
 Toolchain and infrastructure:
 
  - Upgrade to Rust 1.74.1.
 
    The patch release includes a fix for an ICE that the Apple AGX GPU
    driver was hitting.
 
  - Support 'srctree'-relative links in Rust code documentation.
 
  - Automate part of the manual constants handling (i.e. the ones not
    recognised by 'bindgen').
 
  - Suppress searching builtin sysroot to avoid confusion with installed
    sysroots, needed for the to-be-merged arm64 support which uses
    a builtin target.
 
  - Ignore '__preserve_most' functions for 'bindgen'.
 
  - Reduce header inclusion bloat in exports.
 
 'kernel' crate:
 
  - Implement 'Debug' for 'CString'.
 
  - Make 'CondVar::wait()' an uninterruptible wait.
 
 'macros' crate:
 
  - Update 'paste!' to accept string literals.
 
  - Improve '#[vtable]' documentation.
 
 Documentation:
 
  - Add testing section (KUnit and 'rusttest' target).
 
  - Remove 'CC=clang' mentions.
 
  - Clarify that 'rustup override' applies to build directory.

fb249b275c ARM: SoC code changes for 6.8 
There are two notable changes this time:
 
 - Andrew Davis adds a arch/arm/Kconfig.platforms file to simplify
   the platforms that have no code except their Kconfig file
 
 - Linux Walleij removes support for the ARM11MPCore CPU in
   the versatile/realview platform. Since this is the last
   remaining one after removing ox820, some core code can go
   as well.
 
 The other changes are minor cleanups and bugfixes.

f6597d1706 SoC: driver updates for 6.8 
A new drivers/cache/ subsystem is added to contain drivers for abstracting
 cache flush methods on riscv and potentially others, as this is needed for
 handling non-coherent DMA but several SoCs require nonstandard hardware
 methods for it.
 
 op-tee gains support for asynchronous notification with FF-A, as well
 as support for a system thread for executing in secure world.
 
 The tee, reset, bus, memory and scmi subsystems have a couple of minor
 updates.
 
 Platform specific soc driver changes include:
 
  - Samsung Exynos gains driver support for Google GS101 (Tensor G1)
    across multiple subsystems
 
  - Qualcomm Snapdragon gains support for SM8650 and X1E along with
    added features for some other SoCs
 
  - Mediatek adds support for "Smart Voltage Scaling" on MT8186 and MT8195,
    and driver support for MT8188 along with some code refactoring.
 
  - Microchip Polarfire FPGA support for "Auto Update" of the FPGA bitstream
 
  - Apple M1 mailbox driver is rewritten into a SoC driver
 
  - minor updates on amlogic, mvebu, ti, zynq, imx, renesas and hisilicon

c4101e5597 SoC: DT changes for 6.8 
There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
 the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
 already supported chips.
 
 The other six new SoCs are all part of existing arm64 families, but
 are somewhat more interesting:
 
  - Samsung ExynosAutov920 is an automotive chip, and the first one
    we support based on the Cortex-A78AE core with lockstep mode.
 
  - Google gs101 (Tensor G1) is the chip used in a number of Pixel phones,
    and is grouped with Samsung Exynos here since it is based on the same
    SoC design, sharing most of its IP blocks with that series.
 
  - MediaTek MT8188 is a new chip used for mid-range tablets and Chromebooks,
    using two Cortex-A78 cores where the older MT8195 had four of them.
 
  - Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
    phone SoC and the first supported chip based on Cortex-X4, Cortex-A720
    and Cortex-A520.
 
  - Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest
    Laptop chip using the custom Oryon cores.
 
  - Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
    Cortex-A76 and Cortex-A55
 
 In terms of boards, we have
 
  - Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
    G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.
 
  - Multiple Rockchips mobile gaming systems (Anbernic RG351V,
    Powkiddy RK2023, Powkiddy X55) along with the Sonoff iHost Smart
    Home Hub and a few Rockchips SBCs
 
  - Some ComXpress boards based on Marvell CN913x, which is the
    follow-up to Armada 7xxx/8xxx.
 
  - Six new industrial/embedded boards based on NXP i.MX8 and i.MX9
 
  - Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.
 
  - Toradex Verdin AM62 Mallow carrier for TI AM62
 
  - Huashan Pi board based on the SophGo CV1812H RISC-V chip
 
  - Two boards based on Allwinner H616/H618
 
  - A number of reference boards for various added SoCs from Qualcomm,
    Mediatek, Google, Samsung, NXP and Spreadtrum
 
 As usual, there are cleanups and warning fixes across all platforms as
 well as added features for several of them.

Linus Torvalds
3e7aeb78ab Networking changes for 6.8. 
Core & protocols
 ----------------
 
  - Analyze and reorganize core networking structs (socks, netdev,
    netns, mibs) to optimize cacheline consumption and set up
    build time warnings to safeguard against future header changes.
    This improves TCP performances with many concurrent connections
    up to 40%.
 
  - Add page-pool netlink-based introspection, exposing the
    memory usage and recycling stats. This helps indentify
    bad PP users and possible leaks.
 
  - Refine TCP/DCCP source port selection to no longer favor even
    source port at connect() time when IP_LOCAL_PORT_RANGE is set.
    This lowers the time taken by connect() for hosts having
    many active connections to the same destination.
 
  - Refactor the TCP bind conflict code, shrinking related socket
    structs.
 
  - Refactor TCP SYN-Cookie handling, as a preparation step to
    allow arbitrary SYN-Cookie processing via eBPF.
 
  - Tune optmem_max for 0-copy usage, increasing the default value
    to 128KB and namespecifying it.
 
  - Allow coalescing for cloned skbs coming from page pools, improving
    RX performances with some common configurations.
 
  - Reduce extension header parsing overhead at GRO time.
 
  - Add bridge MDB bulk deletion support, allowing user-space to
    request the deletion of matching entries.
 
  - Reorder nftables struct members, to keep data accessed by the
    datapath first.
 
  - Introduce TC block ports tracking and use. This allows supporting
    multicast-like behavior at the TC layer.
 
  - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
    classifiers (RSVP and tcindex).
 
  - More data-race annotations.
 
  - Extend the diag interface to dump TCP bound-only sockets.
 
  - Conditional notification of events for TC qdisc class and actions.
 
  - Support for WPAN dynamic associations with nearby devices, to form
    a sub-network using a specific PAN ID.
 
  - Implement SMCv2.1 virtual ISM device support.
 
  - Add support for Batman-avd mulicast packet type.
 
 BPF
 ---
 
  - Tons of verifier improvements:
    - BPF register bounds logic and range support along with a large
      test suite
    - log improvements
    - complete precision tracking support for register spills
    - track aligned STACK_ZERO cases as imprecise spilled registers. It
      improves the verifier "instructions processed" metric from single
      digit to 50-60% for some programs
    - support for user's global BPF subprogram arguments with few
      commonly requested annotations for a better developer experience
    - support tracking of BPF_JNE which helps cases when the compiler
      transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
      like
    - several fixes
 
  - Add initial TX metadata implementation for AF_XDP with support in
    mlx5 and stmmac drivers. Two types of offloads are supported right
    now, that is, TX timestamp and TX checksum offload.
 
  - Fix kCFI bugs in BPF all forms of indirect calls from BPF into
    kernel and from kernel into BPF work with CFI enabled. This allows
    BPF to work with CONFIG_FINEIBT=y.
 
  - Change BPF verifier logic to validate global subprograms lazily
    instead of unconditionally before the main program, so they can be
    guarded using BPF CO-RE techniques.
 
  - Support uid/gid options when mounting bpffs.
 
  - Add a new kfunc which acquires the associated cgroup of a task
    within a specific cgroup v1 hierarchy where the latter is identified
    by its id.
 
  - Extend verifier to allow bpf_refcount_acquire() of a map value field
    obtained via direct load which is a use-case needed in sched_ext.
 
  - Add BPF link_info support for uprobe multi link along with bpftool
    integration for the latter.
 
  - Support for VLAN tag in XDP hints.
 
  - Remove deprecated bpfilter kernel leftovers given the project
    is developed in user-space (https://github.com/facebook/bpfilter).
 
 Misc
 ----
 
  - Support for parellel TC self-tests execution.
 
  - Increase MPTCP self-tests coverage.
 
  - Updated the bridge documentation, including several so-far
    undocumented features.
 
  - Convert all the net self-tests to run in unique netns, to
    avoid random failures due to conflict and allow concurrent
    runs.
 
  - Add TCP-AO self-tests.
 
  - Add kunit tests for both cfg80211 and mac80211.
 
  - Autogenerate Netlink families documentation from YAML spec.
 
  - Add yml-gen support for fixed headers and recursive nests, the
    tool can now generate user-space code for all genetlink families
    for which we have specs.
 
  - A bunch of additional module descriptions fixes.
 
  - Catch incorrect freeing of pages belonging to a page pool.
 
 Driver API
 ----------
 
  - Rust abstractions for network PHY drivers; do not cover yet the
    full C API, but already allow implementing functional PHY drivers
    in rust.
 
  - Introduce queue and NAPI support in the netdev Netlink interface,
    allowing complete access to the device <> NAPIs <> queues
    relationship.
 
  - Introduce notifications filtering for devlink to allow control
    application scale to thousands of instances.
 
  - Improve PHY validation, requesting rate matching information for
    each ethtool link mode supported by both the PHY and host.
 
  - Add support for ethtool symmetric-xor RSS hash.
 
  - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
    platform.
 
  - Expose pin fractional frequency offset value over new DPLL generic
    netlink attribute.
 
  - Convert older drivers to platform remove callback returning void.
 
  - Add support for PHY package MMD read/write.

de927f6c0b s390 updates for 6.8 merge window 
- Add machine variable capacity information to /proc/sysinfo.
 
 - Limit the waste of page tables and always align vmalloc area size
   and base address on segment boundary.
 
 - Fix a memory leak when an attempt to register interruption sub class
   (ISC) for the adjunct-processor (AP) guest failed.
 
 - Reset response code AP_RESPONSE_INVALID_GISA to understandable
   by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed
   interruption sub class (ISC) registration attempt.
 
 - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED
   response code when enabling interrupts on behalf of a guest.
 
 - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue
   device bound to the vfio_ap device driver when the mediated device is
   attached to a guest, but the queue device is not passed through.
 
 - Rework struct ap_card to hold the whole adjunct-processor (AP) card
   hardware information. As result, all the ugly bit checks are replaced
   by simple evaluations of the required bit fields.
 
 - Improve handling of some weird scenarios between service element (SE)
   host and SE guest with adjunct-processor (AP) pass-through support.
 
 - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return the
   previous value of the to be changed control register. This is useful if
   a bit is only changed temporarily and the previous content needs to be
   restored.
 
 - The kernel starts with machine checks disabled and is expected to enable
   it once trap_init() is called. However the implementation allows machine
   checks early. Consistently enable it in trap_init() only.
 
 - local_mcck_disable() and local_mcck_enable() assume that machine checks
   are always enabled. Instead implement and use local_mcck_save() and
   local_mcck_restore() to disable machine checks and restore the previous
   state.
 
 - Modification of floating point control (FPC) register of a traced
   process using ptrace interface may lead to corruption of the FPC
   register of the tracing process. Fix this.
 
 - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control
   (FPC) register in vCPU, but may lead to corruption of the FPC register
   of the host process. Fix this.
 
 - Use READ_ONCE() to read a vCPU floating point register value from the
   memory mapped area. This avoids that, depending on code generation,
   a different value is tested for validity than the one that is used.
 
 - Get rid of test_fp_ctl(), since it is quite subtle to use it correctly.
   Instead copy a new floating point control register value into its save
   area and test the validity of the new value when loading it.
 
 - Remove superfluous save_fpu_regs() call.
 
 - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines
   provide the vector facility since many years and the need to make the
   task structure size dependent on the vector facility does not exist.
 
 - Remove the "novx" kernel command line option, as the vector code runs
   without any problems since many years.
 
 - Add the vector facility to the z13 architecture level set (ALS).
   All hypervisors support the vector facility since many years.
   This allows compile time optimizations of the kernel.
 
 - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As result,
   the compiled code will have less runtime checks and less code.
 
 - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C.
 
 - Convert the struct subchannel spinlock from pointer to member.

c299010061 asm-generic cleanups for 6.8 
A series from Baoquan He cleans up the asm-generic/io.h to remove the
 ioremap_uc() definition from everything except x86, which still needs it
 for pre-PAT systems. This series notably contains a patch from Jiaxun Yang
 that converts MIPS to use asm-generic/io.h like every other architecture
 does, enabling future cleanups.
 
 Some of my own patches fix -Wmissing-prototype warnings in architecture
 specific code across several architectures. This is now needed as the
 warning is enabled by default. There are still some remaining warnings
 in minor platforms, but the series should catch most of the widely used
 ones make them more consistent with one another.
 
 David McKay fixes a bug in __generic_cmpxchg_local() when this is used
 on 64-bit architectures. This could currently only affect parisc64
 and sparc64.
 
 Additional cleanups address from Linus Walleij, Uwe Kleine-König,
 Thomas Huth, and Kefeng Wang help reduce unnecessary inconsistencies
 between architectures.

a05aea98d4 sysctl-6.8-rc1 
To help make the move of sysctls out of kernel/sysctl.c not incur a size
 penalty sysctl has been changed to allow us to not require the sentinel, the
 final empty element on the sysctl array. Joel Granados has been doing all this
 work. On the v6.6 kernel we got the major infrastructure changes required to
 support this. For v6.7 we had all arch/ and drivers/ modified to remove
 the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only.
 The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches
 are still being reviewed. After that we then can expect also the removal of the
 no longer needed check for procname == NULL.
 
 Let us recap the purpose of this work:
 
   - this helps reduce the overall build time size of the kernel and run time
     memory consumed by the kernel by about ~64 bytes per array
   - the extra 64-byte penalty is no longer inncurred now when we move sysctls
     out from kernel/sysctl.c to their own files
 
 Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further
 work by Thomas Weißschuh with the constificatin of the struct ctl_table.
 
 Due to Joel Granados's work, and to help bring in new blood, I have suggested
 for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward
 to seeing him sent you a pull request for further sysctl changes. This also
 removes Iurii Zaikin as a maintainer as he has moved on to other projects and
 has had no time to help at all.

 happening in this patchset is splitting out various _types.h headers and
 dependency fixups, as well as moving some things out of sched.h to
 better locations.
 
 This is prep work for the memory allocation profiling patchset which
 adds new sched.h interdepencencies.
 
 Testing - it's been in -next, and fixes from pretty much all
 architectures have percolated in - nothing major.

999a36b52b bcachefs updates for 6.8: 
- btree write buffer rewrite: instead of adding keys to the btree write
    buffer at transaction commit time, we know journal them with a
    different journal entry type and copy them from the journal to the
    write buffer just prior to journal write.
 
    This reduces the number of atomic operations on shared cachelines
    in the transaction commit path and is a signicant performance
    improvement on some workloads: multithreaded 4k random writes went
    from ~650k iops to ~850k iops.
 
  - Bring back optimistic spinning for six locks: the new implementation
    doesn't use osq locks; instead we add to the lock waitlist as normal,
    and then spin on the lock_acquired bit in the waitlist entry, _not_
    the lock itself.
 
  - BCH_IOCTL_DEV_USAGE_V2, which allows for new data types
  - BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of fsck
    but without mounting: useful for transparently using the kernel
    version of fsck from 'bcachefs fsck' when the kernel version is a
    better match for the on disk filesystem.
 
  - BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported yet,
    but the passes that are supported are fully featured - errors may be
    corrected as normal.
 
    The new ioctls use the new 'thread_with_file' abstraction for kicking
    off a kthread that's tied to a file descriptor returned to userspace
    via the ioctl.
 
  - btree_paths within a btree_trans are now dynamically growable,
    instead of being limited to 64. This is important for the
    check_directory_structure phase of fsck, and also fixes some issues
    we were having with btree path overflow in the reflink btree.
 
  - Trigger refactoring; prep work for the upcoming disk space accounting
    rewrite
 
  - Numerous bugfixes :)

 ecryptfs from inadvertently mounting case-insensitive filesystems that
 it cannot handle, which would otherwise caused post-mount failures.  It

 As a side note, the optimization to the case-insensitive comparison code
 that you suggested, and the negative dentry support are still on the

acc657692a keys, dns: Fix size check of V1 server-list header 
Fix the size check added to dns_resolver_preparse() for the V1 server-list
header so that it doesn't give EINVAL if the size supplied is the same as
the size of the header struct (which should be valid).

This can be tested with:

        echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @p

which will give "add_key: Invalid argument" without this fix.

6434eade5d Hi, 
Just a couple fixes and no new features. I've been reviewing and testing
 TPM patches for encrypted and integrity protected commuinications [1] but
 they did not made yet to this release.
 
 This was also first release I tested with my still heavily in-development
 test suite for linux integrity [2]. I'm refining this at the moment
 to run keyutils test suite, which could be potentially also run by a Gitlab
 runner for keyutis repository.

68da4c44b9 ext4: fix inconsistent between segment fstrim and full fstrim 
Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with
mininum length of trimmed range set to 8 blocks. If we have say a range of
blocks 10-22 free, this range will not be trimmed because it straddles the
boundary of the two FITRIM ranges and neither part is big enough. This is a
bit surprising to some users that call FITRIM on smaller ranges of blocks
to limit impact on the system. Also XFS trims all free space extents that
overlap with the specified range so we are inconsistent among filesystems.
Let's change ext4_try_to_trim_range() to consider for trimming the whole
free space extent that straddles the end of specified range, not just the
part of it within the range.

1f6bc02f18 ext4: fallback to complex scan if aligned scan doesn't work 
Currently in case the goal length is a multiple of stripe size we use
ext4_mb_scan_aligned() to find the stripe size aligned physical blocks.
In case we are not able to find any, we again go back to calling
ext4_mb_choose_next_group() to search for a different suitable block
group. However, since the linear search always begins from the start,
most of the times we end up with the same BG and the cycle continues.

With large fliesystems, the CPU can be stuck in this loop for hours
which can slow down the whole system. Hence, until we figure out a
better way to continue the search (rather than starting from beginning)
in ext4_mb_choose_next_group(), lets just fallback to
ext4_mb_complex_scan_group() in case aligned scan fails, as it is much
more likely to find the needed blocks.

7c784d6248 ext4: allow for the last group to be marked as trimmed 
The ext4 filesystem tracks the trim status of blocks at the group
level.  When an entire group has been trimmed then it is marked as
such and subsequent trim invocations with the same minimum trim size
will not be attempted on that group unless it is marked as able to be
trimmed again such as when a block is freed.

Currently the last group can't be marked as trimmed due to incorrect
logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
to return the zero based index of the last cluster in a group. This is
then used by ext4_try_to_trim_range() to determine if the trim
operation spans the entire group and as such if the trim status of the
group should be recorded.

ext4_last_grp_cluster() takes a 0 based group index, thus the valid
values for grp are 0..(ext4_get_groups_count - 1). Any group index
less than (ext4_get_groups_count - 1) is not the last group and must
have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
to calculate the number of clusters based on the number of blocks in
the group. Finally subtract 1 from the number of clusters as zero
based indexing is expected.  Rearrange the function slightly to make
it clear what we are calculating and returning.

Reproducer:
// Create file system where the last group has fewer blocks than
// blocks per group
$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
$ mount /dev/nvme0n1 /mnt

Before Patch:
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group not marked as trimmed so second invocation still discards blocks
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed

After Patch:
fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group marked as trimmed so second invocation DOESN'T discard any blocks
fstrim -v /mnt
/mnt: 0 B (0 bytes) trimmed

49f4810356 NFSD 6.8 Release Notes 
The bulk of the patches for this release are clean-ups and minor bug
 fixes.
 
 There is one significant revert to mention: support for RDMA Read
 operations in the server's RPC-over-RDMA transport implementation
 has been fixed so it waits for Read completion in a way that avoids
 tying up an nfsd thread. This prevents a possible DoS vector if an
 RPC-over-RDMA client should become unresponsive during RDMA Read
 operations.
 
 As always I am grateful to NFSD contributors, reviewers, and
 testers.

Pull nfsd updates from Chuck Lever:
 "The bulk of the patches for this release are clean-ups and minor bug
  fixes.

  There is one significant revert to mention: support for RDMA Read
  operations in the server's RPC-over-RDMA transport implementation has
  been fixed so it waits for Read completion in a way that avoids tying
  up an nfsd thread. This prevents a possible DoS vector if an
  RPC-over-RDMA client should become unresponsive during RDMA Read
  operations.

  As always I am grateful to NFSD contributors, reviewers, and testers"

d8c8e595dc dlm for 6.8 
This set cleans up the interface between nfs lockd and dlm, which
 is handling nfs file locking for gfs2 and ocfs2. Very basic lockd
 functionality is fixed, in which the fl owner was using the lockd
 pid instead of the owner value from nfs.

Merge tag 'afs-fix-rotation-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull afs updates from David Howells:
 "The majority of the patches are aimed at fixing and improving the AFS
  filesystem's rotation over server IP addresses, but there are also
  some fixes from Oleg Nesterov for the use of read_seqbegin_or_lock().

   - Fix fileserver probe handling so that the next round of probes
     doesn't break ongoing server/address rotation by clearing all the
     probe result tracking. This could occasionally cause the rotation
     algorithm to drop straight through, give a 'successful' result
     without actually emitting any RPC calls, leaving the reply buffer
     in an undefined state.

     Instead, detach the probe results into a separate struct and
     allocate a new one each time we start probing and update the
     pointer to it. Probes are also sent in order of address preference
     to try and improve the chance that the preferred one will complete
     first.

   - Fix server rotation so that it uses configurable address
     preferences across on the probes that have completed so far than
     ranking them by RTT as the latter doesn't necessarily give the best
     route. The preference list can be altered by writing into
     /proc/net/afs/addr_prefs.

   - Fix the handling of Read-Only (and Backup) volume callbacks as
     there is one per volume, not one per file, so if someone performs a
     command that, say, offlines the volume but doesn't change it, when
     it comes back online we don't spam the server with a status fetch
     for every vnode we're using. Instead, check the Creation timestamp
     in the VolSync record when prompted by a callback break.

   - Handle volume regression (ie. a RW volume being restored from a
     backup) by scrubbing all cache data for that volume. This is
     detected from the VolSync creation timestamp.

   - Adjust abort handling and abort -> error mapping to match better
     with what other AFS clients do.

   - Fix offline and busy volume state handling as they only apply to
     individual server instances and not entire volumes and the rotation
     algorithm should go and look at other servers if available. Also
     make it sleep briefly before each retry if all the volume instances
     are unavailable"
