[PATCH 2/5] xfs: kill mutex_t typedef

To: xfs@xxxxxxxxxxx
Subject: [PATCH 2/5] xfs: kill mutex_t typedef
From: Christoph Hellwig <hch@xxxxxxxxxxxxx>
Date: Wed, 18 Mar 2009 05:41:21 -0400
References: <20090318094119.561416000@xxxxxxxxxxxxxxxxxxxxxx>
User-agent: quilt/0.47-1
People continue to complain about this for weird reasons, but there's
really no point in keeping this typedef for a couple of users anyway.


Signed-off-by: Christoph Hellwig <hch@xxxxxx>
