Subject: [PATCH v2] xfs: fix xfs_bmap_validate_extent_raw when checking attr fork of rt files
Date: Wed, 2 Sep 2020 10:42:48 -0700 [thread overview]
Message-ID: <20200902174248.GU6096@magnolia> (raw)
From: Darrick J. Wong <darrick.wong@oracle.com>
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")
