Subject: sunrpc: fix braino in ->poll()
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=b4301ed560bcb78eae05bfbe76e516bb549861b3;p=linux-edison.git

sunrpc: fix braino in ->poll()

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...
