      Pull perf tools updates from Arnaldo Carvalho de Melo:

      Linus Torvalds authored
      Pull afs updates from David Howells:
       "A collection of fixes to fix afs_cell struct refcounting, thereby
        fixing a slew of related syzbot bugs:
      
         - Fix the cell tree in the netns to use an rwsem rather than RCU.
      
           There seem to be some problems deriving from the use of RCU and a
           seqlock to walk the rbtree, but it's not entirely clear what since
           there are several different failures being seen.
      
           Changing things to use an rwsem instead makes it more robust. The
           extra performance derived from using RCU isn't necessary in this
           case since the only time we're looking up a cell is during mount or
           when cells are being manually added.
      
         - Fix the refcounting by splitting the usage counter into a memory
           refcount and an active users counter. The usage counter was doing
           double duty, keeping track of whether a cell is still in use and
           keeping track of when it needs to be destroyed - but this makes the
           clean up tricky. Separating these out simplifies the logic.
      
         - Fix purging a cell that has an alias. A cell alias pins the cell
           it's an alias of, but the alias is always later in the list. Trying
           to purge in a single pass causes rmmod to hang in such a case.
      
         - Fix cell removal. If a cell's manager is requeued whilst it's
           removing itself, the manager will run again and re-remove itself,
           causing problems in various places. Follow Hillf Danton's
           suggestion to insert a more terminal state that causes the manager
           to do nothing post-removal.
      
        In additional to the above, two other changes:
      
         - Add a tracepoint for the cell refcount and active users count. This
           helped with debugging the above and may be useful again in future.

      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've added new features such as zone capacity for ZNS
        and a new GC policy, ATGC, along with in-memory segment management. In
        addition, we could improve the decompression speed significantly by
        changing virtual mapping method. Even though we've fixed lots of small
        bugs in compression support, I feel that it becomes more stable so
        that I could give it a try in production.
      
        Enhancements:
         - suport zone capacity in NVMe Zoned Namespace devices
         - introduce in-memory current segment management
         - add standart casefolding support
         - support age threshold based garbage collection
         - improve decompression speed by changing virtual mapping method
      
        Bug fixes:
         - fix condition checks in some ioctl() such as compression, move_range, etc
         - fix 32/64bits support in data structures
         - fix memory allocation in zstd decompress
         - add some boundary checks to avoid kernel panic on corrupted image
         - fix disallowing compression for non-empty file
         - fix slab leakage of compressed block writes
      
        In addition, it includes code refactoring for better readability and
        minor bug fixes for compression and zoned device support"

       "A series of patches addressing warnings produced by make htmldocs.
        This includes:
      
         - kernel-doc markup fixes
      
         - ReST fixes
      
         - Updates at the build system in order to support newer versions of
           the docs build toolchain (Sphinx)
      
        After this series, the number of html build warnings should reduce
        significantly, and building with Sphinx 3.1 or later should now be
        supported (although it is still recommended to use Sphinx 2.4.4).
      
        As agreed with Jon, I should be sending you a late pull request by the
        end of the merge window addressing remaining issues with docs build,
        as there are a number of warning fixes that depends on pull requests
        that should be happening along the merge window.
      
        The end goal is to have a clean htmldocs build on Kernel 5.10.
      
        PS. It should be noticed that Sphinx 3.0 is not currently supported,
        as it lacks support for C domain namespaces. Such feature, needed in
        order to document uAPI system calls with Sphinx 3.x, was added only on
        Sphinx 3.1"
