The kernel change literally changes only pipe_write() in fs/pipe.c and this test actually tests inet sockets. I guess that the confusion is caused by the fact that the github issue referenced the lwn.net article as a reason why we need more epoll coverage, but these tests are not directly related to that commit at all. -- Cyril Hrubis chrubis@suse.cz -- Mailing list info: https://lists.linux.it/listinfo/ltp
