Here is the summary with links:
  - [v6,net-next,01/11] skbuff: move __alloc_skb() next to the other skb allocation functions
  - [v6,net-next,02/11] skbuff: simplify kmalloc_reserve()
  - [v6,net-next,03/11] skbuff: make __build_skb_around() return void
  - [v6,net-next,04/11] skbuff: simplify __alloc_skb() a bit
  - [v6,net-next,05/11] skbuff: use __build_skb_around() in __alloc_skb()
  - [v6,net-next,06/11] skbuff: remove __kfree_skb_flush()
  - [v6,net-next,07/11] skbuff: move NAPI cache declarations upper in the file
  - [v6,net-next,08/11] skbuff: introduce {,__}napi_build_skb() which reuses NAPI cache heads
  - [v6,net-next,09/11] skbuff: allow to optionally use NAPI cache from __alloc_skb()
  - [v6,net-next,10/11] skbuff: allow to use NAPI cache from __napi_alloc_skb()
  - [v6,net-next,11/11] skbuff: queue NAPI_MERGED_FREE skbs into NAPI cache instead of freeing

You are awesome, thank you!
