[Qemu-devel] [PATCH for-2.7 0/4] NBD and block alignment fixes

[Eric Blake]

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.

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.

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.
