I've tested f3cfabce7a2e92564d380de3aad4b43901fb7ae6 (Drivers: add blist
flags) from the drivers-for-3.17 branch of scsi-queue
(http://git.infradead.org/users/hch/scsi-queue.git/commit/f3cfabce7a2e92564d380de3aad4b43901fb7ae6
) and this patch still doesn't appear to work (thin provisioning on
Hyper-V's Virtual Disks is not enabled):

At least the virtual disks should have thin_provisioning... I was also
expecting the passthrough SSD to be reported as non-rotational with this patch:
