Well, actually, I was not myself entirely convinced about it... This is the
reason for I wrote "please _don't_ apply this, but tell me what you think about
it.".

>why not use memset() instead ?

Because I simply didn't thought to it :-) .

Hey, that makes fully sense! So far I know, memset() is quicker than 
(or as quick as) a loop, and it remains fully readable (in my opinion :).

Well, such a patch would be :

Thank you for the suggestion.
What do you think of this one?

(Please note that I'm not trying to get a patch for it _by force_ into the
kernel. If it's a bad idea, let's let thing like they currently are, 
the current loop just works.)
