Subject: [GIT PULL] Btrfs updates for 5.1, part 1
Hi,
the branch contains usual mix of new features, core changes and fixes;
full list below. I'm planning 2nd pull request, with a few more fixes
that arrived recently but too close to merge window, will send it next
week.
Please pull, thanks.
New features:
- support zstd compression levels
- new ioctl to unregister a device from the module (ie. reverse of device
scan)
- scrub prints a message to log when it's about to start or finish
Core changes:
- qgroups can now skip part of a tree that does not get updated during
relocation, because this does not affect the quota accounting, estimated
speedup in run time is about 20%
- the compression workspace management had to be enhanced due to zstd
requirements
- various enospc fixes, when there's high fragmentation the
over-reservation can cause ENOSPC that might not happen after a flush,
in such cases try to wait if the situation improves
Fixes:
- various ioctls could overwrite previous return value if copy_to_user
fails, fix this so the original error is reported
- more reclaim vs GFP_KERNEL fixes
- other cleanups and refactoring
- fix a (valid) lockdep warning in a test when device replace is
destroying worker threads
- make qgroup async transaction commit more aggressive, this avoids some
'quota limit reached' errors if there are not enough data to trigger
transaction in order to flush
- fix deadlock between snapshot deletion and quotas when backref walking
is called from context that already holds the same locks
- fsync fixes:
- fix fsync after succession of renames of different files
- fix fsync after succession of renames and unlink/rmdir
