Thanks!

Slight reviewer preference: introduce helpers when they're first used,
as it's a little easier to understand the application without having
to chase new folio_address() -> new slab_address() -> first user of
slab_address() through the patchset.

Yeah would normally do that but with the current folio work going on there
was a chance the helpers would be useful to somebody else too and
cherry-picking a patch that adds them without user is simpler. And indeed
Matthew just asked about virt_to_folio() few days ago :)
