First - thank you for testing, I was struggling to figure out a way to
test this and I somehow missed your email where you managed it.
Second - I think the split checks are worth it. As I've worked through
my private node series, I've learned there are at least a handful of
missing zone device hooks throughout mm - but there is a lot of nuance
between the modes that is frustrating to keep straight.
Every zone device patch helps clarify how coherent-link accelerators
might manage its memory as a numa node, so at the very least I
appreciate it.
