Subject: [PATCH net-next 0/7] some optimization for page pool
Date: Wed, 22 Sep 2021 17:41:24 +0800	[thread overview]
Message-ID: <20210922094131.15625-1-linyunsheng@huawei.com> (raw)

Patch 1: disable dma mapping support for 32-bit arch with 64-bit
         DMA.
Patch 2: support non-split page when PP_FLAG_PAGE_FRAG is set.
patch 3: avoid calling compound_head() for skb frag page
Patch 4-7: use pp_magic to identify pp page uniquely.

V3:
    1. add patch 1/4/6/7.
    2. use pp_magic to identify pp page uniquely too.
    3. avoid unnecessary compound_head() calling.

V2: add patch 2, adjust the commit log accroding to the discussion
    in V1, and fix a compiler error reported by kernel test robot.

Yunsheng Lin (7):
  page_pool: disable dma mapping support for 32-bit arch with 64-bit DMA
  page_pool: support non-split page with PP_FLAG_PAGE_FRAG
  pool_pool: avoid calling compound_head() for skb frag page
  page_pool: change BIAS_MAX to support incrementing
  skbuff: keep track of pp page when __skb_frag_ref() is called
  skbuff: only use pp_magic identifier for a skb' head page
  skbuff: remove unused skb->pp_recycle
