[PATCH 1/4] xfs: move xfs_fs.h to libxfs

To: xfs@xxxxxxxxxxx
Subject: [PATCH 1/4] xfs: move xfs_fs.h to libxfs
From: Dave Chinner <david@xxxxxxxxxxxxx>
Date: Thu, 8 Jan 2015 08:43:00 +1100
Delivered-to: xfs@xxxxxxxxxxx
In-reply-to: <1420666983-7275-1-git-send-email-david@xxxxxxxxxxxxx>
References: <1420666983-7275-1-git-send-email-david@xxxxxxxxxxxxx>
From: Dave Chinner <dchinner@xxxxxxxxxx>

Ioctl API definitions are shared with userspace, so move the header
file that defines them all to libxfs along with all the other code
shared with userspace.
