In retrospect, I definitely agree - I was happy I got coccinelle to work
and a bit too tired to make rationale decisions when I sent the serie as
it's not a kind of thing I'm used to.

For the patch you ack'd, in particular, there would be no gcc warning in
the first place because the source string's size is not known at compile
time and for some reason gcc does not mind silent truncation in that
case, so the usefulnes of the patch is fairly limited in the first
place (it's possibly simpler/good to aim for consistency but that's
about it). I however didn't take the time to make that analysis for all
the patches.

I did think about that, but wasn't sure what was appropriate in this
case.
I now think it would have been better to save everyone a dozen of mails
and wait for the coccinelle patch to land first; but it's a bit late for
regret :)
I'll only catter after the coccinelle script until it lands, so if
anyone is inclined to take one of the rest as they are, great, but
otherwise feel free to ignore them for now.
(In particular, this very patch should not remove the first comment
here, as pointed out by Himanshu Jha in reply to the first patch)


Thanks for taking the time to give feedback,
