Hi,
here's another batch of stability fixes.
The first fix is for the bug you also hit after 6.8-rc2 pull request [1].
We got another report, fortunately it was reproducible and in the end we also
got the fix.
[1] https://lore.kernel.org/linux-btrfs/CAHk-=whNdMaN9ntZ47XRKP6DBes2E5w7fi-0U3H2+PS18p+Pzw@mail.gmail.com/
The rest is usual mix of fixes, zoned mode, device status handling and
error handling.
Please pull, thanks.
- 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
