We don't have a formal self-test framework in-kernel.  Probably much
chin-scratching would precede such a thing.  For now I guess you could
follow Steve and use tools/testing/epoll/.

Perhaps you might go as far as to permit one to type "cd tools/testing
; make test" and have it run all the self-tests.  Which will consist of
epoll ;)
