56ef27e3 unexported page_pool_unlink_napi() and renamed it to page_pool_disable_direct_recycling(). This is because there was no in-tree user of page_pool_unlink_napi(). Since then Rx queue API and an implementation in bnxt got merged. In the bnxt implementation, it broadly follows the following steps: allocate new queue memory + page pool, stop old rx queue, swap, then destroy old queue memory + page pool. The existing NAPI instance is re-used so when the old page pool that is no longer used but still linked to this shared NAPI instance is destroyed, it will trigger warnings. In my initial patches I unlinked a page pool from a NAPI instance directly. Instead, export page_pool_disable_direct_recycling() and call that instead to avoid having a driver touch a core struct.
