2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------
From: Jeff Layton <jlay...@redhat.com>
commit fc87a40677bbe0937e2ff0642c7e83c9a4813f3d upstream.
cifs_find_smb_ses assumes that the vol->password field is a valid
pointer, but that's only the case if a password was passed in via
the options string. It's possible that one won't be if there is
no mount helper on the box.
