X-Git-Tag: v5.15~4083^2~124

xfs: Add missing annotation to xfs_ail_check()

Sparse reports a warning at xfs_ail_check()

warning: context imbalance in xfs_ail_check() - unexpected unlock

The root cause is the missing annotation at xfs_ail_check()

Add the missing __must_hold(&ailp->ail_lock) annotation
