bbff39cc6c hugetlb: allocate vma lock for all sharable vmas
The hugetlb vma lock was originally designed to synchronize pmd sharing. 
As such, it was only necessary to allocate the lock for vmas that were
capable of pmd sharing.  Later in the development cycle, it was discovered
that it could also be used to simplify fault/truncation races as described
in [1].  However, a subsequent change to allocate the lock for all vmas
that use the page cache was never made.  A fault/truncation race could
leave pages in a file past i_size until the file is removed.

Remove the previous restriction and allocate lock for all VM_MAYSHARE
vmas.  Warn in the unlikely event of allocation failure.

ecfbd73387 hugetlb: take hugetlb vma_lock when clearing vma_lock->vma pointer
hugetlb file truncation/hole punch code may need to back out and take
locks in order in the routine hugetlb_unmap_file_folio().  This code could
race with vma freeing as pointed out in [1] and result in accessing a
stale vma pointer.  To address this, take the vma_lock when clearing the
vma_lock->vma pointer.

131a79b474 hugetlb: fix vma lock handling during split vma and range unmapping
Patch series "hugetlb: fixes for new vma lock series".

In review of the series "hugetlb: Use new vma lock for huge pmd sharing
synchronization", Miaohe Lin pointed out two key issues:

1) There is a race in the routine hugetlb_unmap_file_folio when locks
   are dropped and reacquired in the correct order [1].

2) With the switch to using vma lock for fault/truncate synchronization,
   we need to make sure lock exists for all VM_MAYSHARE vmas, not just
   vmas capable of pmd sharing.

These two issues are addressed here.  In addition, having a vma lock
present in all VM_MAYSHARE vmas, uncovered some issues around vma
splitting.  Those are also addressed.

[1] https://lore.kernel.org/linux-mm/01f10195-7088-4462-6def-909549c75ef4@huawei.com/


This patch (of 3):

The hugetlb vma lock hangs off the vm_private_data field and is specific
to the vma.  When vm_area_dup() is called as part of vma splitting, the
vma lock pointer is copied to the new vma.  This will result in issues
such as double freeing of the structure.  Update the hugetlb open vm_ops
to allocate a new vma lock for the new vma.

The routine __unmap_hugepage_range_final unconditionally unset VM_MAYSHARE
to prevent subsequent pmd sharing.  hugetlb_vma_lock_free attempted to
anticipate this by checking both VM_MAYSHARE and VM_SHARED.  However, if
only VM_MAYSHARE was set we would miss the free.  With the introduction of
the vma lock, a vma can not participate in pmd sharing if vm_private_data
is NULL.  Instead of clearing VM_MAYSHARE in __unmap_hugepage_range_final,
free the vma lock to prevent sharing.  Also, update the sharing code to
make sure vma lock is indeed a condition for pmd sharing. 
hugetlb_vma_lock_free can then key off VM_MAYSHARE and not miss any vmas.

14aa8b2d5c mm/mglru: don't sync disk for each aging cycle
wakeup_flusher_threads() was added under the assumption that if a system
runs out of clean cold pages, it might want to write back dirty pages more
aggressively so that they can become clean and be dropped.

However, doing so can breach the rate limit a system wants to impose on
writeback, resulting in early SSD wearout.

94e8ca6ebd remoteproc updates for v6.1
Support for remoteprocs that will perform recovery without help from
 Linux is introduced.
 
 The virtio integration is transitioned towards remoteproc_virtio.c and
 represented by a platform_device, in preparation for instantiating
 virtio instances from DeviceTree.
 
 The iMX remoteproc driver has a couple of sparse warnings corrected and
 a couple of error message printouts are cleaned up. The keystone driver
 is transitioned to use the gpiod API.

Pull io_uring updates from Jens Axboe:

 - Add supported for more directly managed task_work running.

   This is beneficial for real world applications that end up issuing
   lots of system calls as part of handling work. Normal task_work will
   always execute as we transition in and out of the kernel, even for
   "unrelated" system calls. It's more efficient to defer the handling
   of io_uring's deferred work until the application wants it to be run,
   generally in batches.

   As part of ongoing work to write an io_uring network backend for
   Thrift, this has been shown to greatly improve performance. (Dylan)

 - Add IOPOLL support for passthrough (Kanchan)

 - Improvements and fixes to the send zero-copy support (Pavel)

 - Partial IO handling fixes (Pavel)

 - CQE ordering fixes around CQ ring overflow (Pavel)

Support for the VIRTIO_BLK_F_SECURE_ERASE VirtIO feature.

A device that offers this feature can receive VIRTIO_BLK_T_SECURE_ERASE
commands.

A device which supports this feature has the following fields in the
virtio config:

- max_secure_erase_sectors
- max_secure_erase_seg
- secure_erase_sector_alignment

max_secure_erase_sectors and secure_erase_sector_alignment are expressed
in 512-byte units.

Every secure erase command has the following fields:

- sectors: The starting offset in 512-byte units.
- num_sectors: The number of sectors.

90fea5a800 vdpa: device feature provisioning
This patch allows the device features to be provisioned through
netlink. A new attribute is introduced to allow the userspace to pass
a 64bit device features during device adding.

This provides several advantages:

- Allow to provision a subset of the features to ease the cross vendor
  live migration.
- Better debug-ability for vDPA framework and parent.

4959aebba8 virtio-net: use mtu size as buffer length for big packets
Currently add_recvbuf_big() allocates MAX_SKB_FRAGS segments for big
packets even when GUEST_* offloads are not present on the device.
However, if guest GSO is not supported, it would be sufficient to
allocate segments to cover just up the MTU size and no further.
Allocating the maximum amount of segments results in a large waste of
buffer space in the queue, which limits the number of packets that can
be buffered and can result in reduced performance.

Therefore, if guest GSO is not supported, use the MTU to calculate the
optimal amount of segments required.

Below is the iperf TCP test results over a Mellanox NIC, using vDPA for
1 VQ, queue size 1024, before and after the change, with the iperf
server running over the virtio-net interface.

MTU(Bytes)/Bandwidth (Gbit/s)

  1500        22.5     22.4
  9000        12.8     25.9

And result of queue size 256.
MTU(Bytes)/Bandwidth (Gbit/s)
             Before   After
  9000        2.15     11.9

With this patch no degradation is observed with multiple below tests and
feature bit combinations. Results are summarized below for q depth of
1024. Interface MTU is 1500 if MTU feature is disabled. MTU is set to 9000
in other tests.

296ab4a813 net/9p: use a dedicated spinlock for trans_fd
Shamelessly copying the explanation from Tetsuo Handa's suggested
patch[1] (slightly reworded):
syzbot is reporting inconsistent lock state in p9_req_put()[2],
for p9_tag_remove() from p9_req_put() from IRQ context is using
spin_lock_irqsave() on "struct p9_client"->lock but trans_fd
(not from IRQ context) is using spin_lock().

Since the locks actually protect different things in client.c and in
trans_fd.c, just replace trans_fd.c's lock by a new one specific to the
transport (client.c's protect the idr for fid/tag allocations,
while trans_fd.c's protects its own req list and request status field
that acts as the transport's state machine)

riscv: enable THP_SWAP for RV64
I have a Sipeed Lichee RV dock board which only has 512MB DDR, so
memory optimizations such as swap on zram are helpful. As is seen
in commit d0637c505f8a ("arm64: enable THP_SWAP for arm64") and
commit bd4c82c22c367e ("mm, THP, swap: delay splitting THP after
swapped out"), THP_SWAP can improve the swap throughput significantly.

Enable THP_SWAP for RV64, testing the micro-benchmark which is
introduced by commit d0637c505f8a ("arm64: enable THP_SWAP for arm64")
shows below numbers on the Lichee RV dock board:

swp out bandwidth w/o patch: 66908 bytes/ms (mean of 10 tests)
swp out bandwidth w/ patch: 322638 bytes/ms (mean of 10 tests)

Improved by 382%!

ef575281b2 9p/trans_fd: always use O_NONBLOCK read/write
syzbot is reporting hung task at p9_fd_close() [1], for p9_mux_poll_stop()
 from p9_conn_destroy() from p9_fd_close() is failing to interrupt already
started kernel_read() from p9_fd_read() from p9_read_work() and/or
kernel_write() from p9_fd_write() from p9_write_work() requests.

Since p9_socket_open() sets O_NONBLOCK flag, p9_mux_poll_stop() does not
need to interrupt kernel_read()/kernel_write(). However, since p9_fd_open()
does not set O_NONBLOCK flag, but pipe blocks unless signal is pending,
p9_mux_poll_stop() needs to interrupt kernel_read()/kernel_write() when
the file descriptor refers to a pipe. In other words, pipe file descriptor
needs to be handled as if socket file descriptor.

We somehow need to interrupt kernel_read()/kernel_write() on pipes.

A minimal change, which this patch is doing, is to set O_NONBLOCK flag
 from p9_fd_open(), for O_NONBLOCK flag does not affect reading/writing
of regular files. But this approach changes O_NONBLOCK flag on userspace-
supplied file descriptors (which might break userspace programs), and
O_NONBLOCK flag could be changed by userspace. It would be possible to set
O_NONBLOCK flag every time p9_fd_read()/p9_fd_write() is invoked, but still
remains small race window for clearing O_NONBLOCK flag.

If we don't want to manipulate O_NONBLOCK flag, we might be able to
surround kernel_read()/kernel_write() with set_thread_flag(TIF_SIGPENDING)
and recalc_sigpending(). Since p9_read_work()/p9_write_work() works are
processed by kernel threads which process global system_wq workqueue,
signals could not be delivered from remote threads when p9_mux_poll_stop()
 from p9_conn_destroy() from p9_fd_close() is called. Therefore, calling
set_thread_flag(TIF_SIGPENDING)/recalc_sigpending() every time would be
needed if we count on signals for making kernel_read()/kernel_write()
non-blocking.

bc32a6330f The first two changes that involve files outside of fs/ext4:
- submit_bh() can never return an error, so change it to return void,
   and remove the unused checks from its callers
 
 - fix I_DIRTY_TIME handling so it will be set even if the inode
   already has I_DIRTY_INODE
 
 Performance:
 
 - Always enable i_version counter (as btrfs and xfs already do).
   Remove some uneeded i_version bumps to avoid unnecessary nfs cache
   invalidations.
 
 - Wake up journal waters in FIFO order, to avoid some journal users
   from not getting a journal handle for an unfairly long time.
 
 - In ext4_write_begin() allocate any necessary buffer heads before
   starting the journal handle.
 
 - Don't try to prefetch the block allocation bitmaps for a read-only
   file system.
 
 Bug Fixes:
 
 - Fix a number of fast commit bugs, including resources leaks and out
   of bound references in various error handling paths and/or if the fast
   commit log is corrupted.
 
 - Avoid stopping the online resize early when expanding a file system
   which is less than 16TiB to a size greater than 16TiB.
 
 - Fix apparent metadata corruption caused by a race with a metadata
   buffer head getting migrated while it was trying to be read.
 
 - Mark the lazy initialization thread freezable to prevent suspend
   failures.
 
 - Other miscellaneous bug fixes.
 
 Cleanups:
 
 - Break up the incredibly long ext4_full_super() function by
   refactoring to move code into more understandable, smaller
   functions.
 
 - Remove the deprecated (and ignored) noacl and nouser_attr mount
   option.
 
 - Factor out some common code in fast commit handling.
 
 - Other miscellaneous cleanups.

     invalidations

   - Wake up journal waiters in FIFO order, to avoid some journal users
     from not getting a journal handle for an unfairly long time

   - In ext4_write_begin() allocate any necessary buffer heads before
     starting the journal handle

   - Don't try to prefetch the block allocation bitmaps for a read-only
     file system

  Bug Fixes:

   - Fix a number of fast commit bugs, including resources leaks and out
     of bound references in various error handling paths and/or if the
     fast commit log is corrupted

   - Avoid stopping the online resize early when expanding a file system
     which is less than 16TiB to a size greater than 16TiB

   - Fix apparent metadata corruption caused by a race with a metadata
     buffer head getting migrated while it was trying to be read

   - Mark the lazy initialization thread freezable to prevent suspend
     failures

   - Other miscellaneous bug fixes

  Cleanups:

   - Break up the incredibly long ext4_full_super() function by
     refactoring to move code into more understandable, smaller
     functions

   - Remove the deprecated (and ignored) noacl and nouser_attr mount
     option

   - Factor out some common code in fast commit handling

   - Other miscellaneous cleanups"
