[PATCH 00/12] add SMB2 server-side copy support

[David Disseldorp]

This change-set adds support for the FSCTL_SRV_COPYCHUNK and
FSCTL_SRV_REQUEST_RESUME_KEY server-side copy SMB2 ioctls, allowing
for network round-trip avoidance during a file copy, i.e.:
http://www.samba.org/~ddiss/slides/snappery_samba/img17.html

These patches were previously posted alongside the FSRVP and vfs_btrfs
changes, but are more manageable and reviewable as a smaller set.

Feedback appreciated.

Cheers, David
