[PATCH 3/4] xfs: strengthen rmap record flags checking

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

We always know the correct state of the rmap record flags (attr, bmbt,
unwritten) so check them by direct comparison.

Fixes: d852657ccfc0 ("xfs: cross-reference reverse-mapping btree")
