Subject: [KVM-RFC PATCH 0/2] eventfd enhancements for irqfd/iosignalfd

(Applies to kvm.git/master:c27b64a0)

For more details, please read the patch headers.  This series adds
a new feature to eventfd (explicit notifications) which addresses
wqh based limitations, as well as provides fixes for several issues
in irqfd pointed out by Michael Tsirkin.  You can find reference to these
issues here:

This series has been tested against the kvm-eventfd unit test, and
appears to be functioning properly.  You can download this test here:
