kernel - Refactor kern_kevent(), fix timeout overflow (ppoll() bug) (2)
* Certain unsupported EV_ERROR events can cause kern_kevent() to
live-lock, which hits a 'checkloop failed' panic. Silently
deregister such events.
* Complain and deregister any kqueue event on behalf of *poll()
which does not set any poll return flags.
