Hi Dave, thank you for the detailed review.
I've split the patch into 4 separate commits in v3 and addressed
your other feedback:
- Unmount reorder as a standalone patch
- Loop body factored into xfsaild_process_logitem() as a
separate refactoring patch
- Passed ailp instead of dev to tracepoints
- Moved xfs_ail_push_class after xfs_log_item_class events
- Moved UAF-unsafe comments to after xfs_buf_relse()
- Added header comment on xfsaild_push_item() for lifetime rules
v3: https://lore.kernel.org/all/20260308182804.33127-6-ytohnuki@amazon.com/
Please let me know if I've misunderstood any of your points.
