I'm actually not against storing page_pool object ptr directly in
struct-page.  It is a nice optimization.  Perhaps we should implement
this optimization outside this patchset first, and let __xdp_return()
for XDP-redirected packets also take advantage to this optimization?

Then it would feel more natural to also used this optimization in this
patchset, right?

Yes, it would be good if XDP can take advantage of this optimization too.

Then it seems we can remove the "mem_id_ht"? if we want to support different
type of page pool in the future, the type field is in the page pool too
when page_pool object ptr directly in struct-page.
