Re: [PATCH net-next v1 6/6] net: kunit: test netmem, page_pool, and skb frag refcounting

Verify that non-pp (page._refcount / binding->ref) and page_pool
(pp_ref_count) references stay balanced without cross-counter leaks or
underflows across regular pages, page_pool pages, non-pp net_iovs, and
page_pool net_iovs with both pp_recycle=0 and pp_recycle=1.

Cover get/put_net_iov(), get/put_netmem(), napi_pp_get/put_page(),
skb_netmem_ref/unref(), skb_frag_ref/unref(), pskb_copy(),
skb_zerocopy(), skb_shift(), skb_split(), skb_release_data() (clones,
unclone ordering, pskb_extract(), and skb_morph()), and skb_segment().

Per-file breakdown

We're not instructed to pw-bot: cr our patches on patchwork errors for
non-sashiko failures, but it seems the maintainers will want this
fixed anyway, so i'll pw-bot: cr myself and let me know if you don't
want that.
