[PATCH v2] xfs: fix xfs_bmap_validate_extent_raw when checking attr fork of rt files

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

 



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

The realtime flag only applies to the data fork, so don't use the
realtime block number checks on the attr fork of a realtime file.

Fixes: 30b0984d9117 ("xfs: refactor bmap record validation")
