Yes, it can. However, I haven't expanded the rule yet to cover cases when "hidden inside a few function calls" goes outside of one .c or .h file. Coccinelle supports that, but I have to experiment fist if it doesn't bring more false positives that current setup. >Also, we should really have a "make spatch" target so that we can run the thing concurrently with -j80 or somesuch, because as is coccinelle is unbearably slow. The currents rules are very simple, the full run on the whole tree even without any pre-indexing, multithreading and etc. takes around 1 min only.
