Merge tag 'for-5.3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
 "Highlights:

   - chunks that have been trimmed and unchanged since last mount are
     tracked and skipped on repeated trims

   - use hw assissed crc32c on more arches, speedups if native
     instructions or optimized implementation is available

   - the RAID56 incompat bit is automatically removed when the last
     block group of that type is removed

  Fixes:

   - fsync fix for reflink on NODATACOW files that could lead to ENOSPC

   - fix data loss after inode eviction, renaming it, and fsync it

   - fix fsync not persisting dentry deletions due to inode evictions

   - update ctime/mtime/iversion after hole punching

   - fix compression type validation (reported by KASAN)

   - send won't be allowed to start when relocation is in progress, this
     can cause spurious errors or produce incorrect send stream

  Core:

   - new tracepoints for space update

   - tree-checker: better check for end of extents for some tree items

   - preparatory work for more checksum algorithms

   - run delayed iput at unlink time and don't push the work to cleaner
     thread where it's not properly throttled

   - wrap block mapping to structures and helpers, base for further
     refactoring

   - split large files, part 1:
       - space info handling
       - block group reservations
       - delayed refs
       - delayed allocation

   - other cleanups and refactoring"
