Ah, so memcg wasn't doing sanity checks? Is there a cheap way to resolve the question "does this much memory exist"? The "__" versions end up lacking context for why they're "__" versions. I.e. do we want something more descriptive, like __huge_kvmalloc_node() or __unbounded_kvmalloc_node()?
No problem with that, I think "unbounded" is descriptive enough that we can remove the __ too. So that would be kvmalloc_node_unbounded / kvmalloc_array_unbounded / kvcallc_unbounded?
