(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. -Greg --- Davide Libenzi (1): eventfd - revised interface and cleanups (2nd rev) Gregory Haskins (3): KVM: Fix races in irqfd using new eventfd_kref_get interface slow-work: add (module*)work->owner to fix races with module clients kvm: prepare irqfd for having interrupts disabled during eventfd->release drivers/lguest/lg.h | 2 drivers/lguest/lguest_user.c | 4 - fs/aio.c | 24 +--- fs/eventfd.c | 119 ++++++++++++++++++--- include/linux/aio.h | 4 - include/linux/eventfd.h | 18 +-- include/linux/kvm_host.h | 7 + include/linux/slow-work.h | 4 + init/Kconfig | 1 kernel/slow-work.c | 5 + virt/kvm/Kconfig | 1 virt/kvm/eventfd.c | 234 ++++++++++++++++++++++++++++++++---------- 12 files changed, 312 insertions(+), 111 deletions(-) -- Signature -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
