	i don't intend to change behavior of random(3) - for userland.
	i'm just talking about changing behavior of random(9) - for kernel.
	there will be no impact to the behavior of userland random(3).

	there's no srandom() in the kernel, so at this moment there's no
	way for us to get known sequence of (pseudo-)random bytes out of
	kernel random(9).
