This fixes the shadowing of the outer variable rw in the function
io_write(). No issue is caused by this, but let's silence the shadowing
warning anyway.

Running local task_work requires taking uring_lock, for submit + wait we
can try to run them right after submit while we still hold the lock and
save one lock/unlokc pair. The optimisation was implemented in the first
local tw patches but got dropped for simplicity.

io_cqring_wake() needs a barrier for the waitqueue_active() check.
However, in the case of io_req_local_work_add(), we call llist_add()
first, which implies an atomic. Hence we can replace smb_mb() with
smp_mb__after_atomic().

We treat EINPROGRESS like EAGAIN, but if we're retrying post getting
EINPROGRESS, then we just need to check the socket for errors and
terminate the request.

This was exposed on a bluetooth connection request which ends up
taking a while and hitting EINPROGRESS, and yields a CQE result of
-EBADFD because we're retrying a connect on a socket that is now
connected.

Instead of putting io_uring's registered files in unix_gc() we want it
to be done by io_uring itself. The trick here is to consider io_uring
registered files for cycle detection but not actually putting them down.
Because io_uring can't register other ring instances, this will remove
all refs to the ring file triggering the ->release path and clean up
with io_ring_ctx_free().

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)

 "The first two changes involve files outside of fs/ext4:

   - submit_bh() can never return an error, so change it to return void,

   - 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 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

  affs: move from strlcpy with unused retval to strscpy

Pull btrfs updates from David Sterba:
 "There's a bunch of performance improvements, most notably the FIEMAP
  speedup, the new block group tree to speed up mount on large
  filesystems, more io_uring integration, some sysfs exports and the
  usual fixes and core updates.

  Summary:

  Performance:

   - outstanding FIEMAP speed improvement
      - algorithmic change how extents are enumerated leads to orders of
        magnitude speed boost (uncached and cached)
      - extent sharing check speedup (2.2x uncached, 3x cached)
      - add more cancellation points, allowing to interrupt seeking in
        files with large number of extents
      - more efficient hole and data seeking (4x uncached, 1.3x cached)
      - sample results:
	    256M, 32K extents:   4s ->  29ms  (~150x)
	    512M, 64K extents:  30s ->  59ms  (~550x)
	    1G,  128K extents: 225s -> 120ms (~1800x)

   - improved inode logging, especially for directories (on dbench
     workload throughput +25%, max latency -21%)

   - improved buffered IO, remove redundant extent state tracking,
     lowering memory consumption and avoiding rb tree traversal

   - add sysfs tunable to let qgroup temporarily skip exact accounting
     when deleting snapshot, leading to a speedup but requiring a rescan
     after that, will be used by snapper

   - support io_uring and buffered writes, until now it was just for
     direct IO, with the no-wait semantics implemented in the buffered
     write path it now works and leads to speed improvement in IOPS
     (2x), throughput (2.2x), latency (depends, 2x to 150x)

   - small performance improvements when dropping and searching for
     extent maps as well as when flushing delalloc in COW mode
     (throughput +5MB/s)

  User visible changes:

   - new incompatible feature block-group-tree adding a dedicated tree
     for tracking block groups, this allows a much faster load during
     mount and avoids seeking unlike when it's scattered in the extent
     tree items
      - this reduces mount time for many-terabyte sized filesystems
      - conversion tool will be provided so existing filesystem can also
        be updated in place
      - to reduce test matrix and feature combinations requires no-holes
        and free-space-tree (mkfs defaults since 5.15)

   - improved reporting of super block corruption detected by scrub

   - scrub also tries to repair super block and does not wait until next
     commit

   - discard stats and tunables are exported in sysfs
     (/sys/fs/btrfs/FSID/discard)

   - qgroup status is exported in sysfs
     (/sys/sys/fs/btrfs/FSID/qgroups/)

   - verify that super block was not modified when thawing filesystem

  Fixes:

   - FIEMAP fixes
      - fix extent sharing status, does not depend on the cached status
        where merged
      - flush delalloc so compressed extents are reported correctly

   - fix alignment of VMA for memory mapped files on THP

   - send: fix failures when processing inodes with no links (orphan
     files and directories)

   - fix race between quota enable and quota rescan ioctl

   - handle more corner cases for read-only compat feature verification

   - fix missed extent on fsync after dropping extent maps

  Core:

   - lockdep annotations to validate various transactions states and
     state transitions

   - preliminary support for fs-verity in send

   - more effective memory use in scrub for subpage where sector is
     smaller than page

   - block group caching progress logic has been removed, load is now
     synchronous

   - simplify end IO callbacks and bio handling, use chained bios
     instead of own tracking

   - add no-wait semantics to several functions (tree search, nocow,
     flushing, buffered write

   - cleanups and refactoring

  MM changes:

   - export balance_dirty_pages_ratelimited_flags"

Pull ARM devicetree updates from Arnd Bergmann:
 "Most of the changes fall into one of three categories: adding support
  for additional devices on existing machines, cleaning up issues found
  by the ongoing conversion to machine-readable bindings, and addressing
  minor mistakes in the existing DT data.

  Across SoC vendors, Qualcomm and Freescale stick out as getting the
  most updates, which corresponds to their dominance in the mobile phone
  and embedded industrial markets, respectively.

  There are 636 non-merge changeset in this branch, which is a little
  lower than most times, but more importantly we only add 36 machine
  files, which is about half of what we had the past few releases.

  Eight new SoCs are added, but all of them are variations of already
  supported SoC families, and most of them come with one reference board
  design from the SoC vendor:

   - Mediatek MT8186 is a Chromebook/Tablet type SoC, similar to the
     MT65xx series of phone SoCs, with two Cortex-A76 and six Cortex-A55
     cores.

   - TI AM62A is another member of the K3 family with Cortex-A53 cores,
     this one is targetted at Video/Vision processing for industrial and
     automotive applications.

   - NXP i.MX8DXL is another chip for this market in the ever-growing
     i.MX8 family, this one again with two Cortex-A35 cores.

   - Renesas R-Car H3Ne-1.7G (R8A779MB) and R-Car V3H2 (R8A77980A) are
     minor updates of R8A77951 and R8A77980, respectively.

   - Qualcomm IPQ8064-v2.0, IPQ8062 and IPQ8065 are all variants of the
     IPQ8064 chip, with minimally different features.

  The AMD Pensando Elba and Apple M1 Ultra SoC support was getting close
  this time, but in the end did not make the cut.

  The new machines based on existing SoC support are fairly uneventful:

   - Sony Xperia 1 IV is a fairly recent phone based on Qualcomm
     Snapdragon 8 Gen 1.

   - Three Samsung phones based on Snapdragon 410: Galaxy E5, E7 and
     Grand Max. These are added for both 32-bit and 64-bit kernels, as
     they originally shipped running 32-bit code.

   - Two new servers using AST2600 BMCs: AMD DaytonaX and Ampere Mt.
     Mitchell

   - Three new machines based on Rockchips RK3399 and RK3566: Anberic
     RG353P and RG503, Pine64 Pinephone Pro, Open AI Lab

   - Multiple NXP i.MX6/i.MX8 based boards: Kontron SL/BL i.MX8MM OSM-S,
     i.MX8MM Gateworks GW7904, MSC SM2S-IMX8PLUS SoM and carrier board

   - Two development boards in the Microchip AT91 family: SAMA5D3-EDS
     and lan966x-pcb8290.

   - Minor variants of existing boards using Amlogic, Broadcom, Marvell,
     Rockchips, Freescale Layerscape and Socionext Uniphier SoCs"
