9b7c13b83c scsi: dt-bindings: ufs: qcom: Fix ICE phandle
The check for 'qcom,ice' property is wrong. Fix it by checking using
if-required clause and expand the clocks minItems and maxItems for
platforms where 'qcom,ice' is not required so that it includes platforms
with single reg entry and clocks that do not provide an ICE one.

3a8a670eee Networking changes for 6.5.
Core
 ----
 
  - Rework the sendpage & splice implementations. Instead of feeding
    data into sockets page by page extend sendmsg handlers to support
    taking a reference on the data, controlled by a new flag called
    MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
    to invoke an additional callback instead of trying to predict what
    the right combination of MORE/NOTLAST flags is.
    Remove the MSG_SENDPAGE_NOTLAST flag completely.
 
  - Implement SCM_PIDFD, a new type of CMSG type analogous to
    SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
 
  - Enable socket busy polling with CONFIG_RT.
 
  - Improve reliability and efficiency of reporting for ref_tracker.
 
  - Auto-generate a user space C library for various Netlink families.
 
 Protocols
 ---------
 
  - Allow TCP to shrink the advertised window when necessary, prevent
    sk_rcvbuf auto-tuning from growing the window all the way up to
    tcp_rmem[2].
 
  - Use per-VMA locking for "page-flipping" TCP receive zerocopy.
 
  - Prepare TCP for device-to-device data transfers, by making sure
    that payloads are always attached to skbs as page frags.
 
  - Make the backoff time for the first N TCP SYN retransmissions
    linear. Exponential backoff is unnecessarily conservative.
 
  - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
 
  - Avoid waking up applications using TLS sockets until we have
    a full record.
 
  - Allow using kernel memory for protocol ioctl callbacks, paving
    the way to issuing ioctls over io_uring.
 
  - Add nolocalbypass option to VxLAN, forcing packets to be fully
    encapsulated even if they are destined for a local IP address.
 
  - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
    in-kernel ECMP implementation (e.g. Open vSwitch) select the same
    link for all packets. Support L4 symmetric hashing in Open vSwitch.
 
  - PPPoE: make number of hash bits configurable.
 
  - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
    (ipconfig).
 
  - Add layer 2 miss indication and filtering, allowing higher layers
    (e.g. ACL filters) to make forwarding decisions based on whether
    packet matched forwarding state in lower devices (bridge).
 
  - Support matching on Connectivity Fault Management (CFM) packets.
 
  - Hide the "link becomes ready" IPv6 messages by demoting their
    printk level to debug.
 
  - HSR: don't enable promiscuous mode if device offloads the proto.
 
  - Support active scanning in IEEE 802.15.4.
 
  - Continue work on Multi-Link Operation for WiFi 7.
 
 BPF
 ---
 
  - Add precision propagation for subprogs and callbacks. This allows
    maintaining verification efficiency when subprograms are used,
    or in fact passing the verifier at all for complex programs,
    especially those using open-coded iterators.
 
  - Improve BPF's {g,s}setsockopt() length handling. Previously BPF
    assumed the length is always equal to the amount of written data.
    But some protos allow passing a NULL buffer to discover what
    the output buffer *should* be, without writing anything.
 
  - Accept dynptr memory as memory arguments passed to helpers.
 
  - Add routing table ID to bpf_fib_lookup BPF helper.
 
  - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
 
  - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
    maps as read-only).
 
  - Show target_{obj,btf}_id in tracing link fdinfo.
 
  - Addition of several new kfuncs (most of the names are self-explanatory):
    - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
      bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
      and bpf_dynptr_clone().
    - bpf_task_under_cgroup()
    - bpf_sock_destroy() - force closing sockets
    - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
 
 Netfilter
 ---------
 
  - Relax set/map validation checks in nf_tables. Allow checking
    presence of an entry in a map without using the value.
 
  - Increase ip_vs_conn_tab_bits range for 64BIT builds.
 
  - Allow updating size of a set.
 
  - Improve NAT tuple selection when connection is closing.
 
 Driver API
 ----------
 
  - Integrate netdev with LED subsystem, to allow configuring HW
    "offloaded" blinking of LEDs based on link state and activity
    (i.e. packets coming in and out).
 
  - Support configuring rate selection pins of SFP modules.
 
  - Factor Clause 73 auto-negotiation code out of the drivers, provide
    common helper routines.
 
  - Add more fool-proof helpers for managing lifetime of MDIO devices
    associated with the PCS layer.
 
  - Allow drivers to report advanced statistics related to Time Aware
    scheduler offload (taprio).
 
  - Allow opting out of VF statistics in link dump, to allow more VFs
    to fit into the message.
 
  - Split devlink instance and devlink port operations.

One small core feature this time around but mostly driver improvements
 and additions for SPI:
 
  - Add support for controlling the idle state of MOSI, some systems can
    support this and depending on the system integration may need it to
    avoid glitching in some situations.
  - Support for polling mode in the S3C64xx driver and DMA on the
    Qualcomm QSPI driver.
  - Support for several Allwinner SoCs, AMD Pensando Elba, Intel Mount

6e17c6de3d - Yosry Ahmed brought back some cgroup v1 stats in OOM logs.
- Yosry has also eliminated cgroup's atomic rstat flushing.
 
 - Nhat Pham adds the new cachestat() syscall.  It provides userspace
   with the ability to query pagecache status - a similar concept to
   mincore() but more powerful and with improved usability.
 
 - Mel Gorman provides more optimizations for compaction, reducing the
   prevalence of page rescanning.
 
 - Lorenzo Stoakes has done some maintanance work on the get_user_pages()
   interface.
 
 - Liam Howlett continues with cleanups and maintenance work to the maple
   tree code.  Peng Zhang also does some work on maple tree.
 
 - Johannes Weiner has done some cleanup work on the compaction code.
 
 - David Hildenbrand has contributed additional selftests for
   get_user_pages().
 
 - Thomas Gleixner has contributed some maintenance and optimization work
   for the vmalloc code.
 
 - Baolin Wang has provided some compaction cleanups,
 
 - SeongJae Park continues maintenance work on the DAMON code.
 
 - Huang Ying has done some maintenance on the swap code's usage of
   device refcounting.
 
 - Christoph Hellwig has some cleanups for the filemap/directio code.
 
 - Ryan Roberts provides two patch series which yield some
   rationalization of the kernel's access to pte entries - use the provided
   APIs rather than open-coding accesses.
 
 - Lorenzo Stoakes has some fixes to the interaction between pagecache
   and directio access to file mappings.
 
 - John Hubbard has a series of fixes to the MM selftesting code.
 
 - ZhangPeng continues the folio conversion campaign.
 
 - Hugh Dickins has been working on the pagetable handling code, mainly
   with a view to reducing the load on the mmap_lock.
 
 - Catalin Marinas has reduced the arm64 kmalloc() minimum alignment from
   128 to 8.
 
 - Domenico Cerasuolo has improved the zswap reclaim mechanism by
   reorganizing the LRU management.
 
 - Matthew Wilcox provides some fixups to make gfs2 work better with the
   buffer_head code.
 
 - Vishal Moola also has done some folio conversion work.
 
 - Matthew Wilcox has removed the remnants of the pagevec code - their

Pull hardening updates from Kees Cook:
 "There are three areas of note:

  A bunch of strlcpy()->strscpy() conversions ended up living in my tree
  since they were either Acked by maintainers for me to carry, or got
  ignored for multiple weeks (and were trivial changes).

  The compiler option '-fstrict-flex-arrays=3' has been enabled
  globally, and has been in -next for the entire devel cycle. This
  changes compiler diagnostics (though mainly just -Warray-bounds which
  is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
  coverage. In other words, there are no new restrictions, just
  potentially new warnings. Any new FORTIFY warnings we've seen have
  been fixed (usually in their respective subsystem trees). For more
  details, see commit df8fc4e934c12b.

  The under-development compiler attribute __counted_by has been added
  so that we can start annotating flexible array members with their
  associated structure member that tracks the count of flexible array
  elements at run-time. It is possible (likely?) that the exact syntax
  of the attribute will change before it is finalized, but GCC and Clang
  are working together to sort it out. Any changes can be made to the
  macro while we continue to add annotations.

  As an example of that last case, I have a treewide commit waiting with
  such annotations found via Coccinelle:

    https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b

  Also see commit dd06e72e68bcb4 for more details.

* Whenever cpuset needs to rebuild sched_domain, it walked all tasks looking
   for DEADLINE tasks as they need to be accounted on the new domain. Walking
   all tasks can be expensive and there may not be any DEADLINE tasks at all.
   Task iteration is now omitted if there are no DEADLINE tasks.
 
 * Fixes DEADLINE bandwidth misaccounting after task migration failures.
 
 * When no controller is enabled, -Wstringop-overflow warning is triggered.

ed3b7923a8 Scheduler changes for v6.5:
- Scheduler SMP load-balancer improvements:
 
     - Avoid unnecessary migrations within SMT domains on hybrid systems.
 
       Problem:
 
         On hybrid CPU systems, (processors with a mixture of higher-frequency
 	SMT cores and lower-frequency non-SMT cores), under the old code
 	lower-priority CPUs pulled tasks from the higher-priority cores if
 	more than one SMT sibling was busy - resulting in many unnecessary
 	task migrations.
 
       Solution:
 
         The new code improves the load balancer to recognize SMT cores with more
         than one busy sibling and allows lower-priority CPUs to pull tasks, which
         avoids superfluous migrations and lets lower-priority cores inspect all SMT
         siblings for the busiest queue.
 
     - Implement the 'runnable boosting' feature in the EAS balancer: consider CPU
       contention in frequency, EAS max util & load-balance busiest CPU selection.
 
       This improves CPU utilization for certain workloads, while leaves other key
       workloads unchanged.
 
 - Scheduler infrastructure improvements:
 
     - Rewrite the scheduler topology setup code by consolidating it
       into the build_sched_topology() helper function and building
       it dynamically on the fly.
 
     - Resolve the local_clock() vs. noinstr complications by rewriting
       the code: provide separate sched_clock_noinstr() and
       local_clock_noinstr() functions to be used in instrumentation code,
       and make sure it is all instrumentation-safe.
 
 - Fixes:
 
     - Fix a kthread_park() race with wait_woken()
 
     - Fix misc wait_task_inactive() bugs unearthed by the -rt merge:
        - Fix UP PREEMPT bug by unifying the SMP and UP implementations.
        - Fix task_struct::saved_state handling.
 
     - Fix various rq clock update bugs, unearthed by turning on the rq clock
       debugging code.
 
     - Fix the PSI WINDOW_MIN_US trigger limit, which was easy to trigger by
       creating enough cgroups, by removing the warnign and restricting
       window size triggers to PSI file write-permission or CAP_SYS_RESOURCE.

Pull scheduler updates from Ingo Molnar:
 "Scheduler SMP load-balancer improvements:

   - Avoid unnecessary migrations within SMT domains on hybrid systems.

     Problem:

        On hybrid CPU systems, (processors with a mixture of
        higher-frequency SMT cores and lower-frequency non-SMT cores),
        under the old code lower-priority CPUs pulled tasks from the
        higher-priority cores if more than one SMT sibling was busy -
        resulting in many unnecessary task migrations.

     Solution:

        The new code improves the load balancer to recognize SMT cores
        with more than one busy sibling and allows lower-priority CPUs
        to pull tasks, which avoids superfluous migrations and lets
        lower-priority cores inspect all SMT siblings for the busiest
        queue.

   - Implement the 'runnable boosting' feature in the EAS balancer:
     consider CPU contention in frequency, EAS max util & load-balance
     busiest CPU selection.

     This improves CPU utilization for certain workloads, while leaves
     other key workloads unchanged.

  Scheduler infrastructure improvements:

   - Rewrite the scheduler topology setup code by consolidating it into
     the build_sched_topology() helper function and building it
     dynamically on the fly.

   - Resolve the local_clock() vs. noinstr complications by rewriting
     the code: provide separate sched_clock_noinstr() and
     local_clock_noinstr() functions to be used in instrumentation code,
     and make sure it is all instrumentation-safe.

  Fixes:

   - Fix a kthread_park() race with wait_woken()

   - Fix misc wait_task_inactive() bugs unearthed by the -rt merge:
       - Fix UP PREEMPT bug by unifying the SMP and UP implementations
       - Fix task_struct::saved_state handling

   - Fix various rq clock update bugs, unearthed by turning on the rq
     clock debugging code.

   - Fix the PSI WINDOW_MIN_US trigger limit, which was easy to trigger
     by creating enough cgroups, by removing the warnign and restricting
     window size triggers to PSI file write-permission or
     CAP_SYS_RESOURCE.

   - Propagate SMT flags in the topology when removing degenerate domain

   - Fix grub_reclaim() calculation bug in the deadline scheduler code

   - Avoid resetting the min update period when it is unnecessary, in
     psi_trigger_destroy().

   - Don't balance a task to its current running CPU in load_balance(),
     which was possible on certain NUMA topologies with overlapping
     groups.

   - Fix the sched-debug printing of rq->nr_uninterruptible

  Cleanups:

   - Address various -Wmissing-prototype warnings, as a preparation to
     (maybe) enable this warning in the future.

   - Remove unused code

   - Mark more functions __init

   - Fix shadow-variable warnings"

af96134dc8 RCU pull request for v6.5
This pull contains the following branches:
 
 doc.2023.05.10a: Documentation updates
 
 fixes.2023.05.11a: Miscellaneous fixes, perhaps most notably:
 
 o	Remove RCU_NONIDLE().  The new visibility of most of the idle
 	loop to RCU has obsoleted this API.
 
 o	Make the RCU_SOFTIRQ callback-invocation time limit also apply
 	to the rcuc kthreads that invoke callbacks for CONFIG_PREEMPT_RT.
 
 o	Add a jiffies-based callback-invocation time limit to handle
 	long-running callbacks.  (The local_clock() function is only
 	invoked once per 32 callbacks due to its high overhead.)
 
 o	Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs,
 	which fixes a bug that can occur on systems with non-contiguous
 	CPU numbering.
 
 kvfree.2023.05.10a: kvfree_rcu updates
 
 o	Eliminate the single-argument variant of k[v]free_rcu() now
 	that all uses have been converted to k[v]free_rcu_mightsleep().
 
 o	Add WARN_ON_ONCE() checks for k[v]free_rcu*() freeing callbacks
 	too soon.  Yes, this is closing the barn door after the horse
 	has escaped, but Murphy says that there will be more horses.
 
 nocb.2023.05.11a: Callback-offloading updates
 
 o	Fix a number of bugs involving the shrinker and lazy callbacks.

9244724fbf A large update for SMP management:
- Parallel CPU bringup
 
     The reason why people are interested in parallel bringup is to shorten
     the (kexec) reboot time of cloud servers to reduce the downtime of the
     VM tenants.
 
     The current fully serialized bringup does the following per AP:
 
       1) Prepare callbacks (allocate, intialize, create threads)
       2) Kick the AP alive (e.g. INIT/SIPI on x86)
       3) Wait for the AP to report alive state
       4) Let the AP continue through the atomic bringup
       5) Let the AP run the threaded bringup to full online state
 
     There are two significant delays:
 
       #3 The time for an AP to report alive state in start_secondary() on
          x86 has been measured in the range between 350us and 3.5ms
          depending on vendor and CPU type, BIOS microcode size etc.
 
       #4 The atomic bringup does the microcode update. This has been
          measured to take up to ~8ms on the primary threads depending on
          the microcode patch size to apply.
 
     On a two socket SKL server with 56 cores (112 threads) the boot CPU
     spends on current mainline about 800ms busy waiting for the APs to come
     up and apply microcode. That's more than 80% of the actual onlining
     procedure.
 
     This can be reduced significantly by splitting the bringup mechanism
     into two parts:
 
       1) Run the prepare callbacks and kick the AP alive for each AP which
       	 needs to be brought up.
 
 	 The APs wake up, do their firmware initialization and run the low
       	 level kernel startup code including microcode loading in parallel
       	 up to the first synchronization point. (#1 and #2 above)
 
       2) Run the rest of the bringup code strictly serialized per CPU
       	 (#3 - #5 above) as it's done today.
 
 	 Parallelizing that stage of the CPU bringup might be possible in
 	 theory, but it's questionable whether required surgery would be
 	 justified for a pretty small gain.
 
     If the system is large enough the first AP is already waiting at the
     first synchronization point when the boot CPU finished the wake-up of
     the last AP. That reduces the AP bringup time on that SKL from ~800ms
     to ~80ms, i.e. by a factor ~10x.
 
     The actual gain varies wildly depending on the system, CPU, microcode
     patch size and other factors. There are some opportunities to reduce
     the overhead further, but that needs some deep surgery in the x86 CPU
     bringup code.
 
     For now this is only enabled on x86, but the core functionality
     obviously works for all SMP capable architectures.
 
   - Enhancements for SMP function call tracing so it is possible to locate
     the scheduling and the actual execution points. That allows to measure
     IPI delivery time precisely.

          (#3 - #5 above) as it's done today.

          Parallelizing that stage of the CPU bringup might be possible
          in theory, but it's questionable whether required surgery
          would be justified for a pretty small gain.

     If the system is large enough the first AP is already waiting at
     the first synchronization point when the boot CPU finished the
     wake-up of the last AP. That reduces the AP bringup time on that
     SKL from ~800ms to ~80ms, i.e. by a factor ~10x.

     The actual gain varies wildly depending on the system, CPU,
     microcode patch size and other factors. There are some
     opportunities to reduce the overhead further, but that needs some
     deep surgery in the x86 CPU bringup code.

     For now this is only enabled on x86, but the core functionality
     obviously works for all SMP capable architectures.

   - Enhancements for SMP function call tracing so it is possible to
     locate the scheduling and the actual execution points. That allows
     to measure IPI delivery time precisely"

0017387938 Updates for the interrupt subsystem:
- Core:
 
    - Convert the interrupt descriptor storage to a maple tree to overcome
      the limitations of the radixtree + fixed size bitmap. This allows to
      handle real large servers with a huge number of guests without
      imposing a huge memory overhead on everyone.
 
    - Implement optional retriggering of interrupts which utilize the
      fasteoi handler to work around a GICv3 architecture issue.
 
  - Drivers:
 
    - A set of fixes and updates for the Loongson/Loongarch related drivers.
 
    - Workaound for an ASR8601 integration hickup which ends up with CPU
      numbering which can't be represented in the GIC implementation.
 
    - The usual set of boring fixes and updates all over the place.

   simplifies the code and reduces API overhead.  It should also make
   things slightly easier for XFS's upcoming support for fsverity.  It
   does drop fsverity's support for off-CPU hash accelerators, but that
   support was incomplete and not known to be used.
 
 - Update and export fsverity_get_digest() so that it's ready for

Merge tag 'v6.5/vfs.rename.locking' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs rename locking updates from Christian Brauner:
 "This contains the work from Jan to fix problems with cross-directory
  renames originally reported in [1].

  To quickly sum it up some filesystems (so far we know at least about
  ext4, udf, f2fs, ocfs2, likely also reiserfs, gfs2 and others) need to
  lock the directory when it is being renamed into another directory.

  This is because we need to update the parent pointer in the directory
  in that case and if that races with other operations on the directory,
  in particular a conversion from one directory format into another, bad
  things can happen.

  So far we've done the locking in the filesystem code but recently
  Darrick pointed out in [2] that the RENAME_EXCHANGE case was missing.
  That one is particularly nasty because RENAME_EXCHANGE can arbitrarily
  mix regular files and directories and proper lock ordering is not
  achievable in the filesystems alone.

  This patch set adds locking into vfs_rename() so that not only parent
  directories but also moved inodes, regardless of whether they are
  directories or not, are locked when calling into the filesystem.

  This means establishing a locking order for unrelated directories. New
  helpers are added for this purpose and our documentation is updated to
  cover this in detail.

  The locking is now actually easier to follow as we now always lock
  source and target. We've always locked the target independent of
  whether it was a directory or file and we've always locked source if
  it was a regular file. The exact details for why this came about can
  be found in [3] and [4]"

a1257b5e3b Rust changes for v6.5
A fairly small one in terms of feature additions. Most of the changes in
 terms of lines come from the upgrade to the new version of the toolchain
 (which in turn is big due to the vendored 'alloc' crate).
 
  - Upgrade to Rust 1.68.2:
 
    This is the first such upgrade, and we will try to update it often
    from now on, in order to remain close to the latest release, until
    a minimum version (which is "in the future") can be established.
 
    The upgrade brings the stabilization of 4 features we used (and 2
    more that we used in our old 'rust' branch).
 
    Commit 3ed03f4da06e ("rust: upgrade to Rust 1.68.2") contains the
    details and rationale.
 
  - pin-init API:
 
    Several internal improvements and fixes to the pin-init API, e.g.
    allowing to use 'Self' in a struct definition with '#[pin_data]'.
 
  - 'error'  module:
 
    New 'name()' method for the 'Error' type (with 'errname()'
    integration), used to implement the 'Debug' trait for 'Error'.
 
    Add error codes from 'include/linux/errno.h' to the list of Rust
    'Error' constants.
 
    Allow specifying error type on the 'Result' type (with the default
    still being our usual 'Error' type).
 
  - 'str' module:
 
    'TryFrom' implementation for 'CStr', and new 'to_cstring()' method
    based on it.
 
  - 'sync' module:
 
    Implement 'AsRef' trait for 'Arc', allowing to use 'Arc' in code that
    is generic over smart pointer types.
 
    Add 'ptr_eq' method to 'Arc' for easier, less error prone comparison
    between two 'Arc' pointers.
 
    Reword the 'Send' safety comment for 'Arc', and avoid referencing it
    from the 'Sync' one.
 
  - 'task' module:
 
    Implement 'Send' marker for 'Task'.
 
  - 'types' module:
 
    Implement 'Send' and 'Sync' markers for 'ARef<T>' when 'T' is
    'AlwaysRefCounted', 'Send' and 'Sync'.
 
  - Other changes:

Merge tag 'rust-6.5' of https://github.com/Rust-for-Linux/linux

Pull rust updates from Miguel Ojeda:
 "A fairly small one in terms of feature additions. Most of the changes
  in terms of lines come from the upgrade to the new version of the
  toolchain (which in turn is big due to the vendored 'alloc' crate).

  Upgrade to Rust 1.68.2:

   - This is the first such upgrade, and we will try to update it often
     from now on, in order to remain close to the latest release, until
     a minimum version (which is "in the future") can be established.

     The upgrade brings the stabilization of 4 features we used (and 2
     more that we used in our old 'rust' branch).

     Commit 3ed03f4da06e ("rust: upgrade to Rust 1.68.2") contains the
     details and rationale.

  pin-init API:

   - Several internal improvements and fixes to the pin-init API, e.g.
     allowing to use 'Self' in a struct definition with '#[pin_data]'.

  'error' module:

   - New 'name()' method for the 'Error' type (with 'errname()'
     integration), used to implement the 'Debug' trait for 'Error'.

   - Add error codes from 'include/linux/errno.h' to the list of Rust
     'Error' constants.

   - Allow specifying error type on the 'Result' type (with the default
     still being our usual 'Error' type).

  'str' module:

   - 'TryFrom' implementation for 'CStr', and new 'to_cstring()' method
     based on it.

  'sync' module:

   - Implement 'AsRef' trait for 'Arc', allowing to use 'Arc' in code
     that is generic over smart pointer types.

   - Add 'ptr_eq' method to 'Arc' for easier, less error prone
     comparison between two 'Arc' pointers.

   - Reword the 'Send' safety comment for 'Arc', and avoid referencing
     it from the 'Sync' one.

  'task' module:

   - Implement 'Send' marker for 'Task'.

  'types' module:

   - Implement 'Send' and 'Sync' markers for 'ARef<T>' when 'T' is
     'AlwaysRefCounted', 'Send' and 'Sync'.

  Other changes:

   - Documentation improvements and '.gitattributes' change to start
     using the Rust diff driver"
