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...
