From cd514bdaa87e48b52d4074390043f19ce43ea2c4 Mon Sep 17 00:00:00 2001 From: Tim Shimmin Date: Mon, 15 Oct 2007 13:18:59 +1000 Subject: [PATCH] [XFS] Put back the QUEUE_ORDERED_NONE test in the barrier check. Put back the QUEUE_ORDERED_NONE test which caused us grief in sles when it was taken out as, IIRC, it allowed md/lvm to be thought of as supporting barriers when they weren't in some configurations. This patch will be reverting what went in as part of a change for the SGI-pv 964544 (SGI-Modid: xfs-linux-melb:xfs-kern:28568a).
