So you expect users bothered with this to actually get on lkml / write to it
and complain about this? And because not everybody else who is
disgusted with this user-invisible-default-m-module-way-of-solving-this-problem
(when it shouldn't be a module at all) is doing that, it's just "the three"?

It is *shocking* / funny how you *still* want to defend that:

static int __init wait_scan_init(void)
{
	scsi_complete_async_scans();
	return 0;
/* BTW this could've been return scsi_complete_async_scans();
* I see scsi_complete_async_scans() never fails, but still. */
}
late_initcall(wait_scan_init);

deserves/must be a separate module, and that doing:

config SCSI_WAIT_SCAN
	tristate
	default m

is the best way to solve this !!!

In any case, firstly, I'm not a user of SCSI at all. I'm still
interested in this,
but because for me (like I've said twice already) this is simply a (trivial,
perhaps) matter of doing something in the kernel in a better/proper way,
than what is being done currently.

It's also somewhat a matter of *taste* (and hence subjective), if you
_still_ don't get it, Matthew, then there's no point continuing this thread
and trying to convince you ad infinitum.

I do not expect the alternative ways to change this that we've discussed
so far to necessitate any major "fixing up", but yeah a minor touch-up
would clearly be required.
