Subject: [GIT PULL] Btrfs updates for 6.19
Hi,
please pull the following branch with btrfs updates. Thanks.
Features:
- shutdown ioctl support (needs CONFIG_BTRFS_EXPERIMENTAL for now)
- set filesystem state as being shut down (also named going down in
other filesystems), where all active operations return EIO and this
cannot be changed until unmount
- pending operations are attempted to be finished but error messages
may still show up depending on where exactly the shutdown happened
- scrub (and device replace) vs suspend/hibernate
- a running scrub will prevent suspend, which can be annoying as
suspend is an immediate request and scrub is not critical
- filesystem freezing before suspend was not sufficient as the problem
was in process freezing
- behaviour change: on suspend scrub and device replace are cancelled,
where scrub can record the last state and continue from there; the
device replace has to be restarted from the beginning
- zone stats exported in sysfs, from the perspective of the filesystem
this includes active, reclaimable, relocation etc zones
Performance:
- improvements when processing space reservation tickets by optimizing
locking and shrinking critical sections, cumulative improvements in
lockstat numbers show +15%
Notable fixes:
- use vmalloc fallback when allocating bios as high order allocations
can happen with wide checksums (like sha256)
- scrub will always track the last position of progress so it's not
starting from zero after an error
Core:
- under experimental config, checksum calculations are offloaded to
process context, simplifies locking and allows to remove compression
write worker kthread(s)
- speed improvement in direct IO throughput with buffered IO fallback
is +15% when not offloaded but this is more related to internal
crypto subsystem improvements
- this will be probably default in the future removing the sysfs
tunable
- (experimental) block size > page size updates
- support more operations when not using large folios (encoded
read/write and send)
- raid56
- more preparations for fscrypt support
Other:
- more conversions to auto-cleaned variables
- parameter cleanups and removals
- extended warning fixes
- improved printing of structured values like keys
- lots of other cleanups and refactoring
