Subject: [GIT PULL] Btrfs updates for 4.19
Hi,
there are mostly fixes and cleanups, nothing big, though the notable
thing is the inserted/deleted lines delta -1124.
There are no known pending merge conflicts with other trees. Please
pull, thanks.
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
