Correct, looking at the logs AFAICT coccicheck takes 25min on a
relatively beefy machine, and we only run it on path that were actually
modified by pending changes. We get 100+ patches a day, and 40+ series,
and coccicheck fails relatively rarely. So on the NIPA side it's not
worth it.

But, we can certainly integrate it into ingest_mdir.

FTR make htmldocs and of course selftests are also not executed by
ingest_mdir.
