Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull si_code fix from Eric Biederman: "When sorting out the si_code ambiguity fcntl I accidentally overshot and included SIGPOLL as well. Ooops! This is my trivial fix for that. Vince Weaver caught this when it landed in your tree with his perf_event_tests many of which started failing because the si_code changed" Quoth Vince Weaver: "I've tested with this patch applied and can confirm all of my tests now pass again" Fixes: d08477aa975e ("fcntl: Don't use ambiguous SIG_POLL si_codes") * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: fcntl: Don't set si_code to SI_SIGIO when sig == SIGPOLL
