Subject: [PATCH 06/12] xfs: convert xfs_da_do_buf to use irec buffer interface
Date: Wed,  7 Dec 2011 17:18:17 +1100	[thread overview]
Message-ID: <1323238703-13198-7-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1323238703-13198-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

Convert xfs_da_do_buf to use ithe new irec buffer interface. This is
just a simple 1:1 conversion as the irec interface only support
single maps at this point in time.
