+enum batch_kind {

with 'CPU_MEMORY' (instead of plain 'MEMORY') implies future support of 'DEV_MEMORY'?
Maybe, but I don't have an immediate thought on this. CXL "MMIO" that is cachable is a thing but we can also label it as CPU_MEMORY.
We might have something for CC shared/protected memory down the road.
