[PATCH 35/55] xfs: move swap extent code to xfs_extent_ops

To: xfs@xxxxxxxxxxx
Subject: [PATCH 35/55] xfs: move swap extent code to xfs_extent_ops
From: Dave Chinner <david@xxxxxxxxxxxxx>
Date: Thu, 5 Sep 2013 08:05:39 +1000
Delivered-to: xfs@xxxxxxxxxxx
In-reply-to: <1378332359-14737-1-git-send-email-david@xxxxxxxxxxxxx>
References: <1378332359-14737-1-git-send-email-david@xxxxxxxxxxxxx>
From: Dave Chinner <dchinner@xxxxxxxxxx>

Swapping extents is clearly an extent operaiton, and it is not
shared with userspace. Move the code to xfs_extent_ops.[ch], and
the userspace ioctl structure definition to xfs_fs.h where most of
the other ioctl structure definitions are. The means xfs_dfrag.h is
no longer needed in userspace.
