I was mostly referring to the API naming pattern.

Isn't it better if page_pool_alloc is mirrored by netmem_pool_alloc and
netmem_pool_alloc_netmems is mirrored by page_pool_alloc_pages() from
API naming prespective?

And maybe page_pool_alloc_frag can be mirrored by netmem_pool_alloc_frag
in the future?

Also, it would be good to update Documentation/networking/page_pool.rst
for those new netmem APIs, or create a new doc file for them.
