If we had to allow page_pool to be registered twice, via xdp_rxq_info_reg_mem_model() then I guess we could extend page_pool with a usage/users reference count, and then only really free the page_pool when refcnt reach zero. But it just seems and looks wrong (in the code) as the hole trick to get performance is to only have one user.
Let's try this variant. This might be used only in case if no choice. If no issues and provide appropriate comments in the code it can look more a while normal. -- Regards, Ivan Khoronzhuk
