I'm about to send a pull request to Paolo for 2/6 (to go into 5.4) and
I'm preparing a tree of stuff for 5.5 that will include the rest of
the patches.  However, I have been delayed by the fact that multipath
SCSI is currently broken upstream on the P8 test box that I use, so I
haven't been able to test things.

Paul.
