Do we ever use that, though? Having to pass in the pointer, the size and the area just to free memory, sure is a bitch. > but drm_zalloc shouldjust alias to drm_calloc really.. drm_calloc calls kcalloc which performs an integer overflow check on the 'n' and 'size' arguments, which isn't needed for drm_zalloc. Small detail, of course, but I don't see the problem with aliasing to kzalloc.
