Right. No objection to that. Perhaps we should have some sort of special
comment header for our spatches that the script can consume?
// restrict-files: grep -qE 'needs_free_netdev|priv_destructor'
and we'd run that on all files? Or perhaps the API should be more a la
"grep -lE" so we can run it on many files and get a list of matching
