Subject: [PATCH 1/2] xfs: really fix the cursor leak in xfs_alloc_ag_vextent_near
Date: Thu, 12 Jul 2012 07:40:42 +1000	[thread overview]
Message-ID: <1342042843-1773-2-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1342042843-1773-1-git-send-email-david@fromorbit.com>

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.
