OK, I think this might fix it.  It's already queued, but was labelled a mere
"cleanup".

Subject: kmod: use explicit names for waiting
Date: Mon, 16 Mar 2009 10:36:14 +0100
From: Jiri Slaby <jirislaby@...il.com>

Impact: cleanup

As call_usermodehelper accepts enum umh_wait as a wait parameter,
use constants from this enum instead of bool in __request_module.
