But what size should the caller use?
You already explained that the caller cannot use compound_ordet() to
get the size, so what should it be?
Probably this needs to be two flags, PUD and PMD, and the caller should
use the PUD and PMD sizes to figure out how big it is?

[PATCH 00/16] mm/hmm/nouveau: THP mapping and migration
These patches apply to linux-5.8.0-rc1. Patches 1-3 should probably go
into 5.8, the others can be queued for 5.9. Patches 4-6 improve the HMM
self tests. Patch 7-8 prepare nouveau for the meat of this series which
adds support and testing for compound page mapping of system memory
(patches 9-11) and compound page migration to device private memory
(patches 12-16). Since these changes are split
