It's unfortunate the existing names are kmalloc-, dma-kmalloc-, and
kmalloc-rcl- since they aren't following any standard naming convention.

Also not sure I understand the SET_KMALLOC_SIZE naming since this isn't
just setting a size. Maybe better off as INIT_KMALLOC_INFO?

Nothing major though, so:
