Subject: [PATCH 2/5] xfs: lock the AIL before removing the buffer item
Date: Tue, 24 Sep 2013 16:01:13 +1000 [thread overview]
Message-ID: <1380002476-18839-3-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1380002476-18839-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
Regression introduced by commit 46f9d2e ("xfs: aborted buf items can
be in the AIL") which fails to lock the AIL before removing the
item. Spinlock debugging throws a warning about this.
