| H A D | epoll_wakeup_test.c | 282144e0 Mon Apr 06 22:11:20 CDT 2020 Roman Penyaev <rpenyaev@suse.de> kselftest: introduce new epoll test case
This testcase repeats epollbug.c from the bug:
https://bugzilla.kernel.org/show_bug.cgi?id=205933
What it tests? It tests the race between epoll_ctl() and epoll_wait().
New event mask passed to epoll_ctl() triggers wake up, which can be missed
because of the bug described in the link. Reproduction is 100%, so easy
to fix. Kudos, Max, for wonderful test case.
