Removing coccinelle rules because we're seeing slowness somewhere seems
particularly short-sighted to me.
Maybe we do run into intractable problems somewhere with it being slow,
and we'd also like to cater to more "interactive" use.
Agreed. I'm not wild about how long it takes to run either, but if it's
producing useful results, it seems worth it to pay the CPU (and I think
unused.cocci did find some useful results already). There's a point at
which the CPU use becomes intractable, but I don't think we're there
yet.
I am not, either, as it does not look like it is producing all that
useful results these days, but of course, we are looking at the end
result of previous clean-up triggered by these existing rules, and
therefore be biased---we only see cost of running the rules these
days without seeing anything new getting caught.
