2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Willy Tarreau <w...@1wt.eu>
Luis Henriques reported that while backporting commit 40eea80 ("net:
sendmsg: fix NULL pointer dereference") and applying the diff by hand,
I made a typo resulting in the same test being done twice, and msg_name
not being tested.
This fixes cf90357 ("net: sendmsg: fix NULL pointer dereference")
which was merged into 2.6.32.64.
