Hello I just compiled up a fresh git kernel and all of the perf_event_test overflow tests are failing. The reason is that instead of getting POLL_IN or POLL_HUP sources as expected, they are getting weird results in si_code of "-5". I haven't had time to bisect this, but I do notice that some major changes to si_code handling went in with 64a76d0d64bea159da997c002a916ffc03f98bfc Vince
