I meant, the purpose of request_module is to handle dependencies from the
kernel : if we need a functionnality, we request it. It's the definition
of dependency.

But I understood the mechanism by reading some request_module examples.
In fact, we test the avalaibility of the functionnality before calling
the request_module function.

So the case described in my previous message would normally never
happen.

if (!functionnality_not_avalaible) {
	module_request(functionnality)

	if (!functionnality_not_avalaible)
	    goto error;
}

Sorry, so the discussion is closed : forget it :)
