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
