When a receive buffer is not wrapped in an SKB and passed to the network stack, the (compound) page gets freed within the IPA driver. This is currently quite rare. The pages are freed using __free_pages(), but they should instead be freed using page_put(). This series fixes this, in two spots. These patches work for Linux v5.18-rc7 and v5.17.y, but won't apply cleanly to earlier stable branches. (Nevertheless, the fix is trivial.) -Alex
I accidentally based this on net-next/master rather than net/master. Sorry about that. I'll send version 2 in a few days. -Alex
