These apply on top of the previous argument cleanup, documentation, and sanitization patches for irqfd. It would be great to get this queued in next for linux 3.6. I believe I've addressed all the previous comments, including fixing the locking problems in eoifd. I've run this with lockdep adding and removing level irqfd/eoifd pairs without any problems. Please let me know if there are any further comments.
