[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

Concurrent SG_SCSI_RESET ioctls

The sg3_utils command sg_reset --device /dev/sda invokes an ioctl with SG_SCSI_RESET, an argument of SG_SCSI_RESET_DEVICE, on a device opened with O_NDELAY. The call chain is like this: sd_ioctl[sd.c] scsi_nonblockable_ioctl
