After a first pass, I'd say this looks good.

The only thing that needs alot of review and testing is #12,
specifically around how the various COMPARE_AND_WRITE cases work.

Those took a while to get right, although all of the bug-fixes I've hit
using the functional equivalent of patch #6 (in out of tree code) to
allow non SAM_STAT_GOOD 'success' via target_complete_ok_work() with
COMPARE_AND_WRITE have been addressed.

That said, I'm ready to merge the rest of the series ASAP once you're
ready.
