Pull btrfs updates from David Sterba:
 "There are no exciting changes for users, it's been mostly API
  conversions and some fixes or refactoring.

  The mount API conversion is a base for future improvements that would
  come with VFS. Metadata processing has been converted to folios, not
  yet enabling the large folios but it's one patch away once everything
  gets tested enough.

  Core changes:

   - convert extent buffers to folios:
      - direct API conversion where possible
      - performance can drop by a few percent on metadata heavy
        workloads, the folio sizes are not constant and the calculations
        add up in the item helpers
      - both regular and subpage modes
      - data cannot be converted yet, we need to port that to iomap and
        there are some other generic changes required

   - convert mount to the new API, should not be user visible:
      - options deprecated long time ago have been removed: inode_cache,
        recovery
      - the new logic that splits mount to two phases slightly changes
        timing of device scanning for multi-device filesystems
      - LSM options will now work (like for selinux)

   - convert delayed nodes radix tree to xarray, preserving the
     preload-like logic that still allows to allocate with GFP_NOFS

   - more validation of sysfs value of scrub_speed_max

   - refactor chunk map structure, reduce size and improve performance

   - extent map refactoring, smaller data structures, improved
     performance

   - reduce size of struct extent_io_tree, embedded in several
     structures

   - temporary pages used for compression are cached and attached to a
     shrinker, this may slightly improve performance

   - in zoned mode, remove redirty extent buffer tracking, zeros are
     written in case an out-of-order is detected and proper data are
     written to the actual write pointer

   - cleanups, refactoring, error message improvements, updated tests

   - verify and update branch name or tag

   - remove unwanted text"
