Yo,

I notice in module.c:

#ifdef CONFIG_MARKERS
	if (!mod->taints)
		marker_update_probe_range(mod->markers,
			mod->markers + mod->num_markers, NULL, NULL);
#endif

Is this an attempt to not set a marker for proprietary modules? If so,
then this really should be the following conditional instead, because,
really we're not guaranteeing there won't be other taints (e.g. in RHEL
we already have the module signing patch, and then there's also the
TAINT_FORCED_MODULE, which arguably isn't a "taint" for markers):

#ifdef CONFIG_MARKERS
	if (!(mod->taints & TAINT_PROPRIETARY_MODULE))
		marker_update_probe_range(mod->markers,
			mod->markers + mod->num_markers, NULL, NULL);
#endif

Or am I missing something?

Jon.
