there is no spoon either :)

As I said in the previous post, the old klatency works.
As for your rtdm example:
# insmod test-rtdm.ko
test_rtdm: module license 'unspecified' taints kernel.
# I'm alive.I'm alive.I'm alive.I'm alive.I'm alive.I'm alive.I'm
alive.I'm alive.I'm alive.I'm alive.I'm alive.I'm alive.I'm alive.I'm
alive.I'm alive.I'm alive.
seems to work fine too (and I'm even able to rmmod the module).
