If it just recycled\nthe last inflight netmems of a pool being destroyed, page_pool_release()\ncan pass its producer-lock barrier and free the pool before\nrecycle_stat_add() runs.\n\nCommit fcc680a647ba7 (\"page_pool: allow mixing PPs within one bulk\")\nmoved this stat update after the unlock. Commit 271683bb2cf32\n(\"page_pool: Fix use-after-free in page_pool_recycle_in_ring\") later\nadded the barrier, but only fixed page_pool_recycle_in_ring(). Move\nthe update back under the lock.",
