In current form, it doesn't fully prevent regressions, for example the line "except TYPESIGN ucm.c ucma.c" means that new code with such errors to the files ucm.c/ucma.c will be missed too. > > This file + enabling a build bot to run make C=2 allows you to prevent > any checker error types from appearing anywhere in core apart from for > the exception files and starting from this point of. We are talking about the same and our goal is the same too - to see it is merged. I'm just saying that for the IB part, cleanup of IB/core is needed prior to merging IB related runcheck.cfg file, so it will include drivers only. > > > Also, I agree with other reviewers, there is no excuse for adding > > checkpatch specifics per-subsystem/folder, the differences are better > > to be treated in checkpatch.pl itself. > > Hopefully my intention should be clearer if you look at the documentation: > > https://lkml.org/lkml/2017/12/16/135 > > The best is if no exceptions are needed, but until then let's at least get > automatic testing so that you and other reviewers can focus on the more important > issues?
