I appreciate that this is unrelated to your ultimate goal, and that this is somewhat frustrating given the KASAN code is arguably abusing the vmemmap_populate() interface. However, I do think we need to migrate the KASAN code to a proper interface immediately, rather than making it worse in the interim. > If you think I should add these function in this project, than sure I can > send a new version with kasanmap_populate() functions. I would very much appreciate if you could send a version with a kasan_map_populate() interface. I'm more than happy to review/test that portion of the series, or to help if there's some problem which makes that difficult.
