net: refactor sk_page_frag_refill()
While working on virtio_net new allocation strategy to increase payload/truesize ratio, we found that refactoring sk_page_frag_refill() was needed. This patch splits sk_page_frag_refill() into two parts, adding skb_page_frag_refill() which can be used without a socket. While we are at it, add a minimum frag size of 32 for sk_page_frag_refill() Michael will either use netdev_alloc_frag() from softirq context, or skb_page_frag_refill() from process context in refill_work() (GFP_KERNEL allocations) Signed-off-by:Eric Dumazet <edumazet@google.com> Cc: Michael Dalton <mwdalton@google.com> Signed-off-by:
