Subject[PATCH 0/3] scsi: Add Hyper-V logical block provisioning quirks
Microsoft Hyper-V virtual disks currently only claim SPC-2 compliance
even though they implement post SPC-2 features (such as thin
provisioning) which means the Linux kernel does not go on to test for
those features even though they are advertised.

A previous patch attempted to add a quirk to workaround this but the
quirk was only enabled after the features had been scanned for, wouldn't
work for "small" disks and would quirk on all Hyper-V SCSI devices
(e.g. passthrough disks).

The new patches partially revert the previous effort, add the quirk in a
more traditional manner to only Hyper-V virtual disks and work on small
virtual disks.

Sitsofe Wheeler (3):
Revert "Drivers: add blist flags"
scsi: add try_rc16 blacklist flag
scsi: Use try_rc16 and try_vpd_pages quirks on Hyper-V virtual disks
