Subject: [PATCH 3.2 093/221] sunrpc: fix braino in ->poll()

3.2.69-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Al Viro <viro@...IV.linux.org.uk>

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...
