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"
