In what is perhaps a couple lifetimes ago at this point, patches were posted and "mostly" all eventually accepted upstream to support unpriv_sgio on SCSI generic hostdev devices. Since the needed parts of the functionality from the kernel perspective were not yet present upstream, a couple of the patches were not accepted. See: https://www.redhat.com/archives/libvir-list/2015-July/msg00204.html and in particular patches 9 and 10. Since that time it seems things have changed and this essentially reposts those two patches with some minor adjustments in logic in order to "restore" the support. There are lots of interesting tidbits in unreadable by the general public bz's, so I won't include links here.
