Subject: [PATCH] module-init-tools: generate modules.seriomap

Hi Rusty,

I have converted serio bus to use ID matching and changed serio drivers
to use MODULE_DEVICE_TABLE. Now that Vojtech pulled the changes into his
tree it would be nice if official module-init-tools generated the module
map so that hotplug scripts could automatically load proper drivers.

Please consider applying the patch below.

Thanks!

Sure, applied. I would appreciated tests, however: you can download the
testsuite from the same place you get module-init-tools. I don't expect
you to be able to compile for all endian/size combinations, but I can do
that for you.

You should also put the logic into the kernel's scripts/mod/file2alias,
which is where this is supposed to go these days (I haven't removed the
modules.XXX files, since hotplug has enough deployment problems without
me making things worse).

Thanks,
Rusty.

Ok, I will take a look at it but it will take couple of days...

Oh, I see. I wasn't sure where it should go and FC3 hotplug uses modules.*map
so I went that route. What do you think about the patch below then?

I am a little bit confused - is anybody using module aliases at the moment?
I could not find anything on my box...
