Pull xfs updates from Darrick Wong:
 "There's a lot going on this time, which seems about right for this
  drama-filled year.

  Community developers added some code to speed up freezing when
  read-only workloads are still running, refactored the logging code,
  added checks to prevent file extent counter overflow, reduced iolock
  cycling to speed up fsync and gc scans, and started the slow march
  towards supporting filesystem shrinking.

  There's a huge refactoring of the internal speculative preallocation
  garbage collection code which fixes a bunch of bugs, makes the gc
  scheduling per-AG and hence multithreaded, and standardizes the retry
  logic when we try to reserve space or quota, can't, and want to
  trigger a gc scan. We also enable multithreaded quotacheck to reduce
  mount times further. This is also preparation for background file gc,
  which may or may not land for 5.13.

  We also fixed some deadlocks in the rename code, fixed a quota
  accounting leak when FSSETXATTR fails, restored the behavior that
  write faults to an mmap'd region actually cause a SIGBUS, fixed a bug
  where sgid directory inheritance wasn't quite working properly, and
  fixed a bug where symlinks weren't working properly in ecryptfs. We
  also now advertise the inode btree counters feature that was
  introduced two cycles ago.

  Summary:

   - Fix an ABBA deadlock when renaming files on overlayfs.

   - Make sure that we can't overflow the inode extent counters when
     adding to or removing extents from a file.

   - Make directory sgid inheritance work the same way as all the other
     filesystems.

   - Don't drain the buffer cache on freeze and ro remount, which should
     reduce the amount of time if read-only workloads are continuing
     during the freeze.

   - Fix a bug where symlink size isn't reported to the vfs in ecryptfs.

   - Disentangle log cleaning from log covering. This refactoring sets
     us up for future changes to the log, though for now it simply means
     that we can use covering for freezes, and cleaning becomes
     something we only do at unmount.

   - Speed up file fsyncs by reducing iolock cycling.

   - Fix delalloc blocks leaking when changing the project id fails
     because of input validation errors in FSSETXATTR.

   - Fix oversized quota reservation when converting unwritten extents
     during a DAX write.

   - Create a transaction allocation helper function to standardize the
     idiom of allocating a transaction, reserving blocks, locking
     inodes, and reserving quota. Replace all the open-coded logic for
     file creation, file ownership changes, and file modifications to
     use them.

   - Actually shut down the fs if the incore quota reservations get
     corrupted.

   - Fix background block garbage collection scans to not block and to
     actually clean out CoW staging extents properly.

   - Run block gc scans when we run low on project quota.

   - Use the standardized transaction allocation helpers to make it so
     that ENOSPC and EDQUOT errors during reservation will back out,
     invoke the block gc scanner, and try again. This is preparation for
     introducing background inode garbage collection in the next cycle.

   - Combine speculative post-EOF block garbage collection with
     speculative copy on write block garbage collection.

   - Enable multithreaded quotacheck.

   - Allow sysadmins to tweak the CPU affinities and maximum concurrency
     levels of quotacheck and background blockgc worker pools.

   - Expose the inode btree counter feature in the fs geometry ioctl.

   - Cleanups of the growfs code in preparation for starting work on
     filesystem shrinking.

   - Fix all the bloody gcc warnings that the maintainer knows about. :P

   - Fix a RST syntax error.

   - Don't trigger bmbt corruption assertions after the fs shuts down.

   - Restore behavior of forcing SIGBUS on a shut down filesystem when
     someone triggers a mmap write fault (or really, any buffered
     write)"

Pull iomap updates from Darrick Wong:
 "The big change in this cycle is some new code to make it possible for
  XFS to try unaligned directio overwrites without taking locks. If the
  block is fully written and within EOF (i.e. doesn't require any
  further fs intervention) then we can let the unlocked write proceed.
  If not, we fall back to synchronizing direct writes.

  Summary:

   - Adjust the final parameter of iomap_dio_rw.

   - Add a new flag to request that iomap directio writes return EAGAIN
     if the write is not a pure overwrite within EOF; this will be used
     to reduce lock contention with unaligned direct writes on XFS.

Pull erofs updates from Gao Xiang:
 "This contains a somewhat important but rarely reproduced fix reported
  month ago for platforms which have weak memory model (e.g. arm64).

  The root cause is that test_bit/set_bit atomic operations are actually
  implemented in relaxed forms, and uninitialized fields governed by an
  atomic bit could be observed in advance due to memory reordering thus
  memory barrier pairs should be used.

  There is also a trivial fix of crafted blkszbits generated by
  syzkaller.

Pull f2fs updates from Jaegeuk Kim:
 "We've added two major features: 1) compression level and 2)
  checkpoint_merge, in this round.

  Compression level expands 'compress_algorithm' mount option to accept
  parameter as format of <algorithm>:<level>, by this way, it gives a
  way to allow user to do more specified config on lz4 and zstd
  compression level, then f2fs compression can provide higher compress
  ratio.

  checkpoint_merge creates a kernel daemon and makes it to merge
  concurrent checkpoint requests as much as possible to eliminate
  redundant checkpoint issues. Plus, we can eliminate the sluggish issue
  caused by slow checkpoint operation when the checkpoint is done in a
  process context in a cgroup having low i/o budget and cpu shares.

  Enhancements:
   - add compress level for lz4 and zstd in mount option
   - checkpoint_merge mount option
   - deprecate f2fs_trace_io

  Bug fixes:
   - flush data when enabling checkpoint back
   - handle corner cases of mount options
   - missing ACL update and lock for I_LINKABLE flag
   - attach FIEMAP_EXTENT_MERGED in f2fs_fiemap

Pull btrfs updates from David Sterba:
 "This brings updates of space handling, performance improvements or bug
  fixes. The subpage block size and zoned mode features have reached
  state where they're usable but with limitations.

  Performance or related:

   - do not block on deleted block group mutex in the cleaner, avoids
     some long stalls

   - improved flushing: make it work better with ticket space
     reservations and avoid excessive transaction commits in some
     scenarios, slightly improves throughput for random write load

   - preemptive background flushing: separate the logic from ticket
     reservations, improve the accounting and decisions when to flush in
     low space conditions

   - less lock contention related to running delayed refs, let just one
     thread do the flushing when there are many inside transaction
     commit

   - dbench workload improvements: avoid unnecessary work when logging
     inodes, fewer fallbacks to transaction commit and thus less waiting
     for it (+7% throughput, -20% latency)

  Core:

   - subpage block size
      - currently read-only support
      - refactor and generalize code where sectorsize is assumed to be
        page size, add the subpage handling everywhere
      - the read-write support is on the way, page sizes are still
        limited to 4K or 64K

   - zoned mode, first working version but with limitations
      - SMR/ZBC/ZNS friendly allocation mode, utilizing the "no fixed
        location for structures" and chunked allocation
      - superblock as the only fixed data structure needs special
        handling, uses 2 consecutive zones as a ring buffer
      - tree-log support with a dedicated block group to avoid unordered
        writes
      - emulated zones on non-zoned devices
      - not yet working
      - all non-single block group profiles, requires more zone write
        pointer synchronization between the multiple block groups
      - fitrim due to dependency on space cache, can be implemented

  Fixes:

   - ref-verify: proper tree owner and node level tracking

   - fix pinned byte accounting, causing some early ENOSPC now more
     likely due to other changes in delayed refs

  Other:

   - error handling fixes and improvements

   - more error injection points

   - more function documentation

   - more and updated tracepoints

   - subset of W=1 checked by default

   - update comments to allow more automatic kdoc parameter checks"

     Management), based on the existing power capping framework, to
     allow aggregate power constraints to be applied to sets of devices
     in a distributed manner, along with a CPU backend driver based on
     the Energy Model (Daniel Lezcano, Dan Carpenter, Colin Ian King).

   - Add AlderLake Mobile support to the Intel RAPL power capping driver
     and make it use the topology interface when laying out the system
     topology (Zhang Rui, Yunfeng Ye).

   - Drop the cpufreq tango driver belonging to a platform that is not
     supported any more (Arnd Bergmann).

   - Drop the redundant CPUFREQ_STICKY and CPUFREQ_PM_NO_WARN cpufreq
     driver flags (Viresh Kumar).

   - Update cpufreq drivers:

      * Fix max CPU frequency discovery in the intel_pstate driver and
        make janitorial changes in it (Chen Yu, Rafael Wysocki, Nigel
        Christian).

      * Fix resource leaks in the brcmstb-avs-cpufreq driver (Christophe
        JAILLET).

      * Make the tegra20 driver use the resource-managed API (Dmitry
        Osipenko).

      * Enable boost support in the qcom-hw driver (Shawn Guo).

   - Update the operating performance points (OPP) framework:

      * Clean up the OPP core (Dmitry Osipenko, Viresh Kumar).

      * Extend the OPP API by adding new helpers to it (Dmitry Osipenko,
        Viresh Kumar).

      * Allow required OPPs to be used for devfreq devices and update
        the devfreq governor code accordingly (Saravana Kannan).

      * Prepare the framework for introducing new dev_pm_opp_set_opp()
        helper (Viresh Kumar).

      * Drop dev_pm_opp_set_bw() and update related drivers (Viresh
        Kumar).

      * Allow lazy linking of required-OPPs (Viresh Kumar).

   - Simplify and clean up devfreq somewhat (Lukasz Luba, Yang Li,
     Pierre Kuo).

   - Update the generic power domains (genpd) framework:

      * Use device's next wakeup to determine domain idle state (Lina
        Iyer).

      * Improve initialization and debug (Dmitry Osipenko).

      * Simplify computations (Abaci Team).

   - Make janitorial changes in the core code handling system sleep and
     PM-runtime (Bhaskar Chowdhury, Bjorn Helgaas, Rikard Falkeborn,
     Zqiang).

   - Update the MAINTAINERS entry for the exynos cpuidle driver and drop
     DEBUG definition from intel_idle (Krzysztof Kozlowski, Tom Rix).

   - Extend the PM clock layer to cover clocks that must sleep (Nicolas
     Pitre).

   - Update the cpupower utility:

      * Update cpupower command, add support for AMD family 0x19 and
        clean up the code to remove many of the family checks to make
        future family updates easier (Nathan Fontenot, Robert Richter).

      * Add Makefile dependencies for install targets to allow building
        cpupower in parallel rather than serially (Ivan Babrou).

   - Make janitorial changes in power management Kconfig (Lukasz Luba)"

Pull staging and IIO driver updates from Greg KH:
 "Here is the "big" set of staging and IIO driver patches for 5.12-rc1.

  Nothing really huge in here, the number of staging tree patches has
  gone down for a bit, maybe there's only so much churn to happen in
  here at the moment.

  The IIO changes are:

   - new drivers

   - new DT bindings

   - new iio driver features

  with full details in the shortlog.

  The staging driver patches are just a lot of tiny coding style
  cleanups, along with some semi-larger hikey driver cleanups as those
  are _almost_ good enough to get out of the staging tree, but will
  probably have to wait until 5.13 to have happen.

Al root-caused a new warning from syzbot to the ttyprintk tty driver
returning a write count larger than the data the tty layer actually gave
it.  Which confused the tty write code mightily, and with the new
iov_iter based code, caused a WARNING in iov_iter_revert().

syzbot correctly bisected the source of the new warning to commit
9bb48c82 ("tty: implement write_iter"), but the oddity goes back
much further, it just didn't get caught by anything before.
