Subject: [PATCH 3.12 127/175] sunrpc: fix braino in ->poll()

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

3.12-stable 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...
