Subject: [PATCH] xfs: really fix the cursor leak in xfs_alloc_ag_vextent_near
Date: Tue, 3 Jul 2012 17:11:29 +1000 [thread overview]
Message-ID: <1341299489-29747-1-git-send-email-david@fromorbit.com> (raw)
From: Dave Chinner <dchinner@redhat.com>
The current cursor is reallocated when retrying the allocation, so
the existing cursor needs to be destroyed in both the restart and
the failure cases.
