Idea looks OK, but there is already a check in the module that prevents
/dev/kni opened by more than one process [1], did you already removed
that limitation? Or is this something else?

[1]
kni_open(...) {
...
if (test_and_set_bit(KNI_DEV_IN_USE_BIT_NUM, &knet->device_in_use))
	return -EBUSY;
	...
}
