       "Here is the big staging and IIO driver pull request for 5.11-rc1
      
        Lots of different things in here:
      
         - loads of driver updates
      
         - so many coding style cleanups
      
         - new IIO drivers
      
         - Android ION code is finally removed from the tree
      
         - wimax drivers are moved to staging on their way out of the kernel
      
        Nothing really exciting, just the constant grind of kernel development :)

       "Lots of changes (slightly more code increase than usual) at this time,
        while most of code changes are ASoC driver-specific.
      
        Here are some highlights:
      
        Core:
      
         - The new auxiliary bus implementation for Intel DSP, which will be
           used by other drivers as well
      
         - Lots of ASoC core cleanups and refactoring
      
         - UBSAN and KCSAN fixes in rawmidi, sequencer and a few others
      
         - Compress-offload API enhancement for the pause during draining
      
        HD- and USB-audio:
      
         - Enhancements of the USB-audio implicit feedback support, including
           better full-duplex operations
      
         - Continued CA0132 improvements and fixes
      
         - A few new quirk entries, HDMI audio fixes
      
        ASoC:
      
         - Support for boot time selection of Intel DSP firmware, which should
           help distros/users testing new stuff more easily; the kconfig was
           moved to boot time option, too
      
         - Some basic DPCM support in audio graph card
      
         - Removal of old pre-DT Freescale drivers
      
         - Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
           Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek
           RT715, Qualcomm SM8250 and simple GPIO based muxes"

         - sched: support fragmenting IP packets as they come out of conntrack

           enhancements

           in IEEE 802.1Q section 12.14.

        Refactor:
      
         - a few pieces of in_interrupt() cleanup work from Sebastian Andrzej
           Siewior
      
         - phy: add support for shared interrupts; get rid of multiple driver
           APIs and have the drivers write a full IRQ handler, slight growth
           of driver code should be compensated by the simpler API which also
           allows shared IRQs
      
         - add common code for handling netdev per-cpu counters
      
         - move TX packet re-allocation from Ethernet switch tag drivers to a
           central place

      mm: fix fall-through warnings for Clang · 01359eb2
      Gustavo A. R. Silva authored
      In preparation to enable -Wimplicit-fallthrough for Clang, fix a couple of
      warnings by explicitly adding a break statement instead of just letting
      the code fall through to the next, and by adding a fallthrough
      pseudo-keyword in places where the code is intended to fall through.

      mm: fix kernel-doc markups · a00cda3f
      Mauro Carvalho Chehab authored
      Kernel-doc markups should use this format:
              identifier - description
      
      Fix some issues on mm files:
      
      1) The definition for get_user_pages_locked() doesn't follow it.  Also,
         it expects a short descrpition at the header, followed by a long one,
         after the parameters.  Fix it.
      
      2) Kernel-doc requires that a kernel-doc markup to be immediately below
         the function prototype, as otherwise it will rename it.  So, move
         get_pfnblock_flags_mask() description to the right place.
      
      3) Make invalidate_mapping_pagevec() to also follow the expected
         kernel-doc format.
      
      While here, fix a few minor English syntax issues, as suggested
      by Matthew:

      zram: break the strict dependency from lzo · 3d711a38
      Rui Salvaterra authored
      From the beginning, the zram block device always enabled CRYPTO_LZO,
      since lzo-rle is hardcoded as the fallback compression algorithm.  As a
      consequence, on systems where another compression algorithm is chosen
      (e.g.  CRYPTO_ZSTD), the lzo kernel module becomes unused, while still
      having to be built/loaded.
      
      This patch removes the hardcoded lzo-rle dependency and allows the user
      to select the default compression algorithm for zram at build time.  The
      previous behaviour is kept, as the default algorithm is still lzo-rle.

      Currently, zram supports the stat via /sys/block/zram/mm_stat to represent
      how many of incompressible pages are stored at the moment but it couldn't
      show how many times incompressible pages were wrote down since zram set
      up.  It's also good indication to see how zram is effective in the system.

      Minchan Kim authored
      There is demand to writeback specific process pages to backing store
      instead of all idles pages in the system due to storage wear out concerns
      and to launching latency of apps which are most of the time idle but are
      critical for resume latency.
