(Applies to kvm.git/master:4631e094)
The following is the latest attempt to fix the remaining races in irqfd/eventfd. For more details, please read the patch headers.
This series has been tested against the kvm-eventfd unit test, and appears to be functioning properly. You can download this test here:
ftp://ftp.novell.com/dev/ghaskins/kvm-eventfd.tar.bz2
I've included version 2 of Davide's eventfd patch (ported to kvm.git) so that its a complete reviewable series. Note, however, that there may be later versions of his patch to consider for merging, so we should coordinate with him.
Note also that I potentially found an issue in slow_work which I subsequently fixed, so I have cc'd David Howells. It is needed to close some of the remaining issues.
