Subject: [GIT PULL] Btrfs updates for 5.8
Hi,
please pull the following updates to btrfs. Thanks.
Highlights:
- speedup dead root detection during orphan cleanup, eg. when there are
many deleted subvolumes waiting to be cleaned, the trees are now looked
up in radix tree instead of a O(N^2) search
- snapshot creation with inherited qgroup will mark the qgroup
inconsistent, requires a rescan
- send will emit file capabilities after chown, this produces a stream
that does not need postprocessing to set the capabilities again
- direct io ported to iomap infrastructure, cleaned up and simplified
code, notably removing last use of struct buffer_head in btrfs code
Core changes:
- factor out backreference iteration, to be used by ordinary
backreferences and relocation code
- improved global block reserve utilization
* better logic to serialize requests
* increased maximum available for unlink
* improved handling on large pages (64K)
- direct io cleanups and fixes
* simplify layering, where cloned bios were unnecessarily created for
some cases
* error handling fixes (submit, endio)
* remove repair worker thread, used to avoid deadlocks during
repair
- refactored block group reading code, preparatory work for new type of
block group storage that should improve mount time on large filesystems
Cleanups:
- cleaned up (and slightly sped up) set/get helpers for metadata data
structure members
- root bit REF_COWS got renamed to SHAREABLE to reflect the that the
blocks of the tree get shared either among subvolumes or with the
relocation trees
Fixes:
- when subvolume deletion fails due to ENOSPC, the filesystem is not
turned read-only
- device scan deals with devices from other filesystems that changed
ownership due to overwrite (mkfs)
- fix a race between scrub and block group removal/allocation
- fix long standing bug of a runaway balance operation, printing the same
line to the syslog, caused by a stale status bit on a reloc tree that
prevented progress
- fix corrupt log due to concurrent fsync of inodes with shared extents
- fix space underflow for NODATACOW and buffered writes when it for some
reason needs to fallback to COW mode
