Subject: [PATCH] xfs: fix xfs_bmap_validate_extent_raw when checking attr fork
of rt files
Git-commit: d0c20d38af135b2b4b90aa59df7878ef0c8fbef4
Patch-mainline: v5.9-rc4
References: git-fixes
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")
