Subject: [PATCH 14/14] xfs: remove sv wrappers
Date: Mon, 29 Nov 2010 12:38:32 +1100	[thread overview]
Message-ID: <1290994712-21376-15-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1290994712-21376-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

The sv_t type is no longer used in XFS. Remove the header file defining the
wrapper and the fragments that still reference it.

Signed-off-by: Dave Chinner <dchinner@redhat.com>
