Merge tag 'for-4.19-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
 "Mostly fixes and cleanups, nothing big, though the notable thing is
  the inserted/deleted lines delta -1124.

  User visible changes:
   - allow defrag on opened read-only files that have rw permissions;
     similar to what dedupe will allow on such files

  Core changes:
   - tree checker improvements, reported by fuzzing:
      * more checks for: block group items, essential trees
      * chunk type validation
      * mount time cross-checks that physical and logical chunks match
      * switch more error codes to EUCLEAN aka EFSCORRUPTED

  Fixes:
   - fsync corner case fixes

   - fix send failure when root has deleted files still open

   - send, fix incorrect file layout after hole punching beyond eof

   - fix races between mount and deice scan ioctl, found by fuzzing

   - fix deadlock when delayed iput is called from writeback on the same
     inode; rare but has been observed in practice, also removes code

   - fix pinned byte accounting, using the right percpu helpers; this
     should avoid some write IO inefficiency during low space conditions

   - don't remove block group that still has pinned bytes

   - reset on-disk device stats value after replace, otherwise this
     would report stale values for the new device

  Cleanups:
   - time64_t/timespec64 cleanups

   - remove remaining dead code in scrub handling NOCOW extents after
     disabling it in previous cycle

   - simplify fsync regarding ordered extents logic and remove all the
     related code

   - remove redundant arguments in order to reduce stack space
     consumption

   - remove support for V0 type of extents, not in use since 2.6.30

   - remove several unused structure members

   - fewer indirect function calls by inlining some callbacks

   - qgroup rescan timing fixes

   - vfs: iget cleanups"
