Merge tag 'for-5.13-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"The updates this time are mostly stabilization, preparation and minor
improvements.
User visible improvements:
- readahead for send, improving run time of full send by 10% and for
incremental by 25%
- make reflinks respect O_SYNC, O_DSYNC and S_SYNC flags
- export supported sectorsize values in sysfs (currently only page
size, more once full subpage support lands)
- more graceful errors and warnings on 32bit systems when logical
addresses for metadata reach the limit posed by unsigned long in
page::index
- error: fail mount if there's a metadata block beyond the limit
- error: new metadata block would be at unreachable address
- warn when 5/8th of the limit is reached, for 4K page systems
it's 10T, for 64K page it's 160T
- zoned mode
- relocated zones get reset at the end instead of discard
- automatic background reclaim of zones that have 75%+ of unusable
space, the threshold is tunable in sysfs
Fixes:
- fsync and tree mod log fixes
- fix inefficient preemptive reclaim calculations
- fix exhaustion of the system chunk array due to concurrent
allocations
- fix fallback to no compression when racing with remount
- preemptive fix for dm-crypt on zoned device that does not properly
advertise zoned support
Core changes:
- add inode lock to synchronize mmap and other block updates (eg.
deduplication, fallocate, fsync)
- kmap conversions to new kmap_local API
- subpage support (continued)
- new helpers for page state/extent buffer tracking
- metadata changes now support read and write
- error handling through out relocation call paths
- many other cleanups and code simplifications"
