Thread-topic: [Xen-devel] [PATCH 0/5] pvSCSI (SCSI pass through) driver

Yep, its certainly a candidate for 3.2, but I'd class the API as
"experimental" at this stage and not commit to supporting it going
forward as-is just yet.

Things I'd like to see: 
 * performance results (hopefully at the summit!)
 * variable sized comms rings (fixed at connect time) so we can queue
more descriptors if req'd.
 * support for pass through of individual scsi logical units to the
dom0's linux scsi-generic layer rather than whole HBAs -- I think most
users will want to hide all that FC nastiness and just present a LUN.

Best,
Ian
