Since the bug which commit 8b48ec23 ("md: don't unregister sync_thread
with reconfig_mutex held") fixed is related with action_store path, other
callers which reap sync_thread didn't need to be changed.

Let's pull md_unregister_thread from md_reap_sync_thread, then fix previous
bug with belows.

1. unlock mddev before md_reap_sync_thread in action_store.
2. save reshape_position before unlock, then restore it to ensure position
   not changed accidentally by others.

Boot-time assembly of arrays with md= command-line arguments breaks when
CONFIG_BLOCK_LEGACY_AUTOLOAD is unset. md_setup_drive() in md-autodetect.c
calls blkdev_get_by_dev(), assuming this implicitly creates the block
device.

Fix this by attempting to md_alloc() the array first. As in the probe path,
ignore any error as failure is caught by blkdev_get_by_dev() anyway.

The mdadm test 07layouts randomly produces a kernel hung task deadlock.
The deadlock is caused by the suspend_lo/suspend_hi files being set by
the mdadm background process during reshape and not being cleared
because the process hangs. (Leaving aside the issue of the fragility of
freezing kernel tasks by buggy userspace processes...)

When the background mdadm process hangs it, is waiting (without a
timeout) on a change to the sync_completed file signalling that the
reshape has completed. The process is woken up a couple times when
the reshape finishes but it is woken up before MD_RECOVERY_RUNNING
is cleared so sync_completed_show() reports 0 instead of "none".

To fix this, notify the sysfs file in md_reap_sync_thread() after
MD_RECOVERY_RUNNING has been cleared. This wakes up mdadm and causes
it to continue and write to suspend_lo/suspend_hi to allow IO to
continue.

The 07layouts test in mdadm fails on some systems. The failure
presents itself as the backup file not being removed before the next
layout is grown into:

  mdadm: /dev/md0: cannot create backup file /tmp/md-test-backup:
      File exists

This is because the background mdadm process, which is responsible for
cleaning up this backup file gets into an infinite loop waiting for
the reshape to start. mdadm checks the mdstat file if a reshape is
going and, if it is not, it waits for an event on the file or times
out in 5 seconds. On faster machines, the reshape may complete before
the 5 seconds times out, and thus the background mdadm process loops
waiting for a reshape to start that has already occurred.

mdadm reads the mdstat file to start, but mdstat does not report that the
reshape has begun, even though it has indeed begun. So the mdstat_wait()
call (in mdadm) which polls on the mdstat file won't ever return until
timing out.

The reason mdstat reports the reshape has started is due to an issue
in status_resync(). recovery_active is subtracted from curr_resync which
will result in a value of zero for the first chunk of reshaped data, and
the resulting read will report no reshape in progress.

To fix this, if "resync - recovery_active" is an overloaded value, force
the value to be MD_RESYNC_ACTIVE so the code reports a resync in progress.

The only place that uses RCU to access conf->log is in
r5l_log_disk_error(). This function is mostly used in the IO path
and once with mddev_lock() held in raid5_change_consistency_policy().

It is known that the IO will be suspended before the log is freed and
r5l_log_exit() is called with the mddev_lock() held.

This should mean that conf->log can not be freed while the function is
being called, so the RCU protection is not necessary. Drop the
rcu_read_lock() as well as the synchronize_rcu() and

The raid5-cache code relies on there being no IO in flight when
log_exit() is called. There are two places where this is not
guaranteed so add mddev_suspend() and mddev_resume() calls to these
sites.

The site in raid5_change_consistency_policy() is in the error path,
and another similar call site already has suspend/resume calls just
below it; so it should be equally safe to make that change here.

There is one remaining site in raid5_remove_disk() that we call log_exit()
without suspending the array. Unfortunately, as the comment stated, we
cannot call mddev_suspend from raid5d.

We usually do all our bitmap IO in units of PAGE_SIZE.

With very small or oddly sized external meta data, or with
PAGE_SIZE != 4k, it can happen that our last on-disk bitmap page
is not fully PAGE_SIZE aligned, so we may need to adjust the size
of the IO.

We used to do that with
  min_t(unsigned int, PAGE_SIZE,
	last_allowed_sector - current_offset);
And for just the right diff, (unsigned int)(diff) will result in 0.

A bio of length 0 will correctly be rejected with an IO error
(and some scary WARN_ON_ONCE()) by the scsi layer.

Do the calculation properly.

  io_uring does support buffered writes on any file type, but since the
  buffered write path just always -EAGAIN (or -EOPNOTSUPP) any attempt
  to do so if IOCB_NOWAIT is set, any buffered write will effectively be
  handled by io-wq offload. This isn't very efficient, and we even have
  specific code in io-wq to serialize buffered writes to the same inode
  to avoid further inefficiencies with thread offload.

  This is particularly sad since most buffered writes don't block, they
  simply copy data to a page and dirty it. With this pull request, we
  can handle buffered writes a lot more effiently.

  If balance_dirty_pages() needs to block, we back off on writes as
  indicated.

  This improves buffered write support by 2-3x.

   as well. The code is organized a lot better like this, and io_uring.c
   is now < 4K LOC (me).

 - Deprecate the epoll_ctl opcode. It'll still work, just trigger a
   warning once if used. If we don't get any complaints on this, and I

   (me).

   - Fix array underflow in prep_lookup_table (Dan Carpenter).

   - Add static annotation to the k3_j72xx_bandgap_j7* data structure
     (Jin Xiaoyun).

   - Fix typos in comments detected on sun8i by Coccinelle (Julia
     Lawall).

   - Fix typos in comments on rzg2l (Biju Das).

   - Remove as unnecessary call to dev_err() as the error is already

Pull spi updates from Mark Brown:
 "The big update this time around is some excellent work from David
  Jander who went through the fast path and really eliminated overheads,
  meaning that we are seeing a huge reduction in the time spent between
  transfers for single threaded clients.

  Benchmarking has been coming out at about a halving of overhead which
  is clearly visible in system level usage that stresses SPI like some
  CAN and IIO applications, especially with small transfers. Thanks to
  David for taking the time to drill down into this and push the work
  upstream.

Pull ARM boardfile deprecation from Arnd Bergmann:
 "Over the past ten years, new machine support was based on device tree,
  and an initial set of about 400 boards using ATAGS with boardfile for
  booting were grandfathered in, with about half of them either removed
  or converted to DT over time.

  Based on the recent mailing list discussion I started, I have now
  turned the findings into a set of patches that marks most board files
  as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.

  For the boards that are marked as unused, there are two final chances
  for potential users: The removal is scheduled to take place after the
  longterm stable kernel at the end of 2022, so users can stay on that
  version for another few years, and if anyone still has one of these
  machines and is planning to keep updating kernels beyond that version,
  they can speak up now to have their boards taken off the list again.

  Waiting for the LTS release also makes sure that there will be at
  least one longterm kernel that contains the recent multiplatform
  conversion along while still supporting all legacy boards.

  The short summary of the current status is:

   - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
     users and will be removed entirely.

   - The mmp and davinci platforms have DT support for the important
     machines and will become DT-only after this.

   - s3c64xx, dove, orion5x, and pxa keep some board files to allow
     those to be migrated over to DT more easily, but most board files
     are getting removed now. DT support on these platforms is partially
     working but requires changes to additional drivers for the other
     boards.

   - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the
     moment but have some boards with known users. Removing the board
     files that nobody uses should make it easier to try a DT conversion
     if anyone cares.

  There is no explicit timeline what happens with the boards that remain
  after this removal, but I expect to revisit this in the future, and
  with most boards gone, there will be a good time to do a treewide
  review of platform drivers that never gained DT support and have no
  remaining in-tree board files"

Pull ARM DT updates from Arnd Bergmann:
 "As usual, the bulk of the changes for the SoC tree are devicetree file
  updates, and most of these changes are for 64-bit embedded machines.
  As before, there are a ton of style cleanups, and additional hardware
  support for existing machines.

  Looking only at the new SoC, the notable additions are:

   - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
     BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
     BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes
     with a corresponding reference board.

   - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
     i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65
     NPU.

   - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of
     Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The
     SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets
     added here in addition to the reference boards.

     such mishap was observed in the wild.

Pull scheduler updates from Ingo Molnar:
"Load-balancing improvements:

   - Improve NUMA balancing on AMD Zen systems for affine workloads.

   - Improve the handling of reduced-capacity CPUs in load-balancing.

   - Energy Model improvements: fix & refine all the energy fairness
     metrics (PELT), and remove the conservative threshold requiring 6%
     energy savings to migrate a task. Doing this improves power
     efficiency for most workloads, and also increases the reliability
     of energy-efficiency scheduling.

   - Optimize/tweak select_idle_cpu() to spend (much) less time
     searching for an idle CPU on overloaded systems. There's reports of
     several milliseconds spent there on large systems with large
     workloads ...

     [ Since the search logic changed, there might be behavioral side
       effects. ]

   - Improve NUMA imbalance behavior. On certain systems with spare
     capacity, initial placement of tasks is non-deterministic, and such
     an artificial placement imbalance can persist for a long time,
     hurting (and sometimes helping) performance.

     The fix is to make fork-time task placement consistent with runtime
     NUMA balancing placement.

     Note that some performance regressions were reported against this,
     caused by workloads that are not memory bandwith limited, which
     benefit from the artificial locality of the placement bug(s). Mel
     Gorman's conclusion, with which we concur, was that consistency is
     better than random workload benefits from non-deterministic bugs:

        "Given there is no crystal ball and it's a tradeoff, I think
         it's better to be consistent and use similar logic at both fork
         time and runtime even if it doesn't have universal benefit."

   - Improve core scheduling by fixing a bug in
     sched_core_update_cookie() that caused unnecessary forced idling.

   - Improve wakeup-balancing by allowing same-LLC wakeup of idle CPUs
     for newly woken tasks.

   - Fix a newidle balancing bug that introduced unnecessary wakeup
     latencies.

  ABI improvements/fixes:

   - Do not check capabilities and do not issue capability check denial
     messages when a scheduler syscall doesn't require privileges. (Such
     as increasing niceness.)

   - Add forced-idle accounting to cgroups too.

   - Fix/improve the RSEQ ABI to not just silently accept unknown flags.
     (No existing tooling is known to have learned to rely on the
     previous behavior.)

   - Depreciate the (unused) RSEQ_CS_FLAG_NO_RESTART_ON_* flags.

  Optimizations:

   - Optimize & simplify leaf_cfs_rq_list()

   - Micro-optimize set_nr_{and_not,if}_polling() via try_cmpxchg().

  Misc fixes & cleanups:

   - Fix the RSEQ self-tests on RISC-V and Glibc 2.35 systems.

   - Fix a full-NOHZ bug that can in some cases result in the tick not
     being re-enabled when the last SCHED_RT task is gone from a
     runqueue but there's still SCHED_OTHER tasks around.

   - Various PREEMPT_RT related fixes.
