Merge tag 'for-6.9-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
- fix race when reading extent buffer and 'uptodate' status is missed
by one thread (introduced in 6.5)
- do additional validation of devices using major:minor numbers
- zoned mode fixes:
- use zone-aware super block access during scrub
- fix use-after-free during device replace (found by KASAN)
- also delete zones that are 100% unusable to reclaim space
- extent unpinning fixes:
- fix extent map leak after error handling
- print correct range in error message
- error code and message updates
