[PATCH 1/9] Use xfs.h rather than libxfs.h

To: xfs@xxxxxxxxxxx
Subject: [PATCH 1/9] Use xfs.h rather than libxfs.h
From: Eric Sandeen <sandeen@xxxxxxxxxxx>
Date: Wed, 27 May 2009 13:53:25 -0500
Cc: Eric Sandeen <sandeen@xxxxxxxxxxx>
In-reply-to: <1243450413-12681-1-git-send-email-sandeen@xxxxxxxxxxx>
References: <1243450413-12681-1-git-send-email-sandeen@xxxxxxxxxxx>
Use xfs/xfs.h when possible rather than xfs/libxfs.h,
now that libxfs.h isn't part of a normal xfsprogs-devel
install.
