I have actual bad experience with this :) v4 of this patch series excluded 'compat/' from the conversion, but the semantic patch is applied to 'compat/' all the same, resulting in failed CI builds because of the four 'extern's in 'compat/obstack.h', and will continue to do so. (Coccinelle has no issues with those other header files; I guess those are not included in the '.c' source files we analyze with Coccinelle in a stock Linux build environment). > I'm happy to _see_ it, as > it's important to show how the transformation was done.
