(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 (Note: I believe either the eventfd solution in 2/3, or the patch that Davide has proposed should work equally well. Its purely a question of which direction we want to go in w.r.t. the wakeup registration). --- Gregory Haskins (3): KVM: Fix races in irqfd using new eventfd_kref_get interface eventfd: add internal reference counting to fix notifier race conditions kvm: prepare irqfd for having interrupts disabled during eventfd->release fs/eventfd.c | 43 ++++++++++-- include/linux/eventfd.h | 7 ++ virt/kvm/eventfd.c | 173 +++++++++++++++++++++++++++++------------------ 3 files changed, 150 insertions(+), 73 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
