Having real function names in your commit message won't make it more useful.
IMHO, the problem is you're still using a template commit message,
which produces
a robot-like commit message.

Developers don't like that, we prefer to see a text written by some
guy explaining
why is this patch needed, and what it's fixing/improving from an
overall point of view.
This is not easy and takes much training.

I believe patches should help maintainers, not only add work them,
so it's important to double-triple-check the patch and
double-triple-check the commit message.

I know this is tedious and it'll slow you a bit. But it's a good
thing: it means you are working :-)

Also, in this particular case, where the coccinelle does not fix
something obvious,
then I'd say you should be *extra* careful.

Hope this helps.
