Subject: xfs: move swap extent code to xfs_extent_ops
X-Git-Tag: v3.2.0-alpha1~22
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e334fb793b1f4aedf04926f17ee0179f48e55315;p=thirdparty%2Fxfsprogs-dev.git

xfs: move swap extent code to xfs_extent_ops

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.
