Subject[KVM PATCH v2 0/2] irqfd: use POLLHUP notification for close()
(Applies to kvm.git/master:25deed73)

Please see the header for 2/2 for a description. This patch series has been
fully tested and appears to be working correctly.

[Review notes:
*) Paul has looked at the SRCU design and, to my knowledge, didn't find
any holes.
*) Michael, Avi, and myself agree that while the removal of the DEASSIGN
vector is not desirable, the fix on close() is more important in
the short-term. We can always add DEASSIGN support again in the
future with a CAP bit.


*) Pulled in Davide's official patch for 1/2 from his submission
accepted into -mmotm.
*) Fixed patch 2/2 to use the "key" field as a bitmap in the wakeup
logic, per Davide's feedback.

*) Initial release
