This is a respin of the patches originally proposed yesterday, called "[KVM-RFC PATCH 0/2] eventfd enhancements for irqfd/iosignalfd", which you can find a link to the thread here: http://www.gossamer-threads.com/lists/linux/kernel/1091852 Aside from introducing a few minor fixes (patches 1/4, 2/4), the general solution for module reference counting has been extracted from the (controversial) SRCU enhancement. We can address the SRCU topic at a later time. For now, fixing the race condition is a higher priority item IMO. Hopefully, this more focused series is more palatable for the reviewers/maintainers involved. --- Gregory Haskins (4): eventfd: add module reference counting support for registered notifiers eventfd: add generalized notifier interface KVM: fix irqfd error checking KVM: update inaccurate irqfd comment fs/eventfd.c | 77 ++++++++++++++++++++++++++++++++++++++++++++ include/linux/eventfd.h | 37 +++++++++++++++++++++ virt/kvm/eventfd.c | 82 ++++++++++++++++++----------------------------- 3 files changed, 146 insertions(+), 50 deletions(-) --
