Yes, eventually. My initial intention a few month ago was to remove the ugly casts [1], but then willy pointed out that Linus objected to something like this [2] and it looks like more than a decade old technical debt. Since there are more than 600 or those it will take a while to convert suitable gfp calls to kmalloc. Afterwards we can re-evaluate what APIs we want to provide for allocations that must have actual pages.
