This series extracts a couple of bug fixes that should be included in 2.7, out of my earlier v5 NBD series [1] that was deemed too large and too late. Then it tackles the promised regression fix reported by Peter for Dell Equallogic iSCSI SANs with their unusual non-power-of-2 unmap granularity.
[1] https://lists.gnu.org/archive/html/qemu-devel/2016-07/msg04053.html The earlier series had a couple other patches that are borderline bug fixes, but I think they can wait for 2.8, as follows: https://lists.gnu.org/archive/html/qemu-devel/2016-07/msg04054.html 8/14 nbd: Let server know when client gives up Servers already have to deal with clients like qemu 2.6 that don't give this notification, so it doesn't hurt to keep 2.7 in that same situation. https://lists.gnu.org/archive/html/qemu-devel/2016-07/msg04064.html 12/14 nbd: Improve server handling of shutdown requests Clients already have to deal with servers like qemu 2.6 that don't reply to NBD_OPT_ABORT, so it doesn't hurt to keep 2.7 in that same situation.
