Here's the latest iteration of adding an interface to assert and
de-assert level interrupts from external drivers like vfio. 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. Thanks,
Alex
