It looks like eventpoll uses the dynamic minor stuff (.minor =
MISC_DYNAMIC_MINOR), so it could well be that this is just what it got
on his system due to something else loading and requesting a dynamic
minor before eventpoll loaded. A better check (if one is necessary)
might be to see if the minor of the leaked device is different from the
minor of the epoll device right after creation.

RPMs are now in that directory.

Are there any downsides to doing this?
