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
