Subject: [PATCH 3/4] xfs: default attr fork size does not handle device inodes
Date: Tue, 6 Apr 2021 21:59:22 +1000 [thread overview]
Message-ID: <20210406115923.1738753-4-david@fromorbit.com> (raw)
In-Reply-To: <20210406115923.1738753-1-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
Device inodes have a non-default data fork size of 8 bytes
as checked/enforced by xfs_repair. xfs_default_attroffset() doesn't
handle this, so lets do a minor refactor so it does.
Fixes: e6a688c33238 ("xfs: initialise attr fork on inode create")
