Thanks for your feedback. Here's what I will do for v2, unless you find more
typos or areas for improvement:

	/*
	 * Kernel code should not call syscalls (i.e., sys_xyzyyz()) directly.
	 * Instead, use one of the functions which work equivalently, such as
	 * the ksys_xyzyyz() functions prototyped below.
	 */

Thanks,
	Dominik
