    Subject[PATCH 3.16.y-ckt 095/165] sunrpc: fix braino in ->poll()
    Date
    3.16.7-ckt9 -stable review patch.  If anyone has any objections, please let me know.

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

    From: Al Viro <viro@ZenIV.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...
