bcachefs: Don't trace should_be_locked unless changing (2025-06-11 23:25:41 -0400)
----------------------------------------------------------------
bcachefs fixes for 6.16-rc2
As usual, highlighting the ones users have been noticing:
- Fix a small issue with has_case_insensitive not being propagated on
snapshot creation; this led to fsck errors, which we're harmless
because we're not using this flag yet (it's for overlayfs +
casefolding).
- Log the error being corrected in the journal when we're doing fsck
repair: this was one of the "lessons learned" from the i_nlink 0 ->
subvolume deletion bug, where reconstructing what had happened by
analyzing the journal was a bit more difficult than it needed to be.
- Don't schedule btree node scan to run in the superblock: this fixes a
regression from the 6.16 recovery passes rework, and let to it running
unnecessarily.
The real issue here is that we don't have online, "self healing" style
topology repair yet: topology repair currently has to run before we go
RW, which means that we may schedule it unnecessarily after a
transient error. This will be fixed in the future.
- We now track, in btree node flags, the reason it was scheduled to be
rewritten. We discovered a deadlock in recovery when many btree nodes
need to be rewritten because they're degraded: fully fixing this will
take some work but it's now easier to see what's going on.
For the bug report where this came up, a device had been kicked RO due
to transient errors: manually setting it back to RW was sufficient to
allow recovery to succeed.
- Mark a few more fsck errors as autofix: as a reminder to users, please
do keep reporting cases where something needs to be repaired and is
not repaired automatically (i.e. cases where -o fix_errors or fsck -y
is required).
- rcu_pending.c now works with PREEMPT_RT
- 'bcachefs device add', then umount, then remount wasn't working - we
now emit a uevent so that the new device's new superblock is correctly
picked up
- Assorted repair fixes: btree node scan will no longer incorrectly
update sb->version_min,
- Assorted syzbot fixes
