Well, I don't have strong opinion about this exact statement, but

	Ingo, COULD YOU PLEASE PERSONALLY FUCKING STOP THIS
	CHECKPATCH.PL-AS-INDICATOR HORSESHIT !

Every damn single warning in this case is about whitespace or 80 column limit.

Every damn single one!

The hacker of your calibre should know the difference between whitespace-bad code
and bug-ridden-bad code.


What are those unacceptable mistakes?

Don't read the code again, what are those mistakes?


I _very_ briefly looked at prng.c and place I find wrong it passing
"int nbytes" to get_prng_bytes(). It should be unsigned at least.

checkpatch.pl says about this? Suuuure, it does...
