Looks good to me, a few comments in the patches. As mentioned privately, I think we should write a dummy char driver that allows us to exercise all types of poll (single, poll, pollfree, etc) and be able to trigger the error paths with it too. I'll give that a shot. We can probably just make it a debugfs file or something like that, and have it be configurable too as a debug option for test purposes. -- Jens Axboe
