From: Al Viro <viro@ZenIV.linux.org.uk>
3.4.108-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit 1711fd9addf214823b993468567cab1f8254fc51 upstream.
POLL_OUT isn't what callers of ->poll() are expecting to see; it's actually __SI_POLL | 2 and it's a siginfo code, not a poll bitmap bit...
