Subject: [KVM PATCH v4 0/4] irqfd fixes
Date: Tue, 23 Jun 2009 18:40:32 -0400 [thread overview]
Message-ID: <20090623223717.5254.22497.stgit@dev.haskins.net> (raw)
(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.
