Subject: [ 132/133] cifs: reinstate the forcegid option

3.5-stable review patch.  If anyone has any objections, please let me know.

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

From: Jeff Layton <jlayton@...hat.com>

commit 72bd481f860f0125c810bb43d878ce5f9c060c58 upstream.

Apparently this was lost when we converted to the standard option
parser in 8830d7e07a5e38bc47650a7554b7c1cfd49902bf
