Dave to the rescue.... :-)

That option works perfectly well.  I had actually hacked the kernel
source to set the default but the kernel command-line is less
invasive.

Thanks to everyone for the input.

Best wishes for a pleasant week.

built-into the kernel.  Reported by <greg@enjellic.com>.

So are you going to also add a mention of this fact to every single
place in the documentation that talks about some arbitrary module
option?

That doesn't make any sense, and neither does this patch.

It's better to make it more apparent that module options can
be set on the kernel command line when something is compiled
statically into the kernel.

That way it only needs to be explained in one place, not in
several.

I'm not applying this.

I guess Documentation/kernel-parameters.txt is where such things
live, can I send you a patch for that or does it need to go
through someone else?

I think lkml is a suitable place to submit something like
that.

Sure, but if it's networking parameters, you (David) could still merge it...

It's not about networking parameters.

It's about adding a generic mention somewhere central that you can set
"module parameters" on the kernel command line when a module is built
statically into the kernel.

OK, I didn't see the patch itself, sorry.

Maybe like this, from that same file:

Module parameters for modules that are built into the kernel image
are specified on the kernel command line with the module name plus
'.' plus parameter name, with '=' and value if appropriate, such as:

	usbcore.blinkenlights=1



I'll search for the patch...
