Re: [PATCH v6 net-next 00/11] skbuff: introduce skbuff_heads bulking and reusing

Hello:

This series was applied to netdev/net-next.git (refs/heads/master):

On Sat, 13 Feb 2021 14:10:43 +0000 you wrote:

Currently, all sorts of skb allocation always do allocate
skbuff_heads one by one via kmem_cache_alloc().
On the other hand, we have percpu napi_alloc_cache to store
skbuff_heads queued up for freeing and flush them by bulks.

We can use this cache not only for bulk-wiping, but also to obtain
heads for new skbs and avoid unconditional allocations, as well as
for bulk-allocating (like XDP's cpumap code and veth driver already
do).
