Do this, under both 2.6.26 and 2.6.27.

2.6.26 will put a working driver into initrd.

2.6.27 will put a dead driver into initrd (because no firmware got copied into initrd image).

I believe your claim is untrue. It uses the distribution's tool to
create the initrd, doesn't it? And those tools _do_ handle the
MODULE_FIRMWARE() tags and pull in appropriate firmware.

slackware's CURRENT mkinitrd and kernel-modules scripts appear to disprove your claims. And yes, they use a modern kernel, 2.6.24.


They've had to
get that right for _years_ already.

You should not just /assume/ that everything is ok, simply because time passed since request_firmware() was added. Or let impatience blind you to the breakage that will result from your change.

Further, there are several factors that clearly differentiate a driver that has been using request_firmware() for a while, and newly converting a large block of drivers en masse.
