2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Dan Carpenter <[email protected]>

commit cb26a24ee9706473f31d34cc259f4dcf45cd0644 upstream.

info->num comes from the user.  It's type int.  If the user passes
in a negative value that would cause memory corruption.
