Hi Jason,
Just run off the original tests with this patch (eventpoll.c from
4.5-rc2 + patch bellow). Got the same good results, no regression.

PS,
Original cases 0m24.953s vs 0m41.826s now probably is related with my
pc
setup. As I just now re-run test with original patch, got the same ~41
sec.
So I am fine with this patch!
Thanks, I shall add your Tested-by:
One thing we're sorely missing is an epoll test suite, in
tools/testing/selftests. If anyone has anything which we can use to
kick things off, please hand it over ;)
Not bad idea, probably we need a "tools/testing/selftests/eventpoll"
folder under which we should have test cases for various epoll scenarios
with common "run.sh". In spare time I can try to build a case for
EXCLUSIVE flag (with queues & multiple processes :) ).
Thanks,
Madars
