Subject: [Patch bpf-next v2 0/5] sock_map: clean up and refactor code for BPF_SK_SKB_VERDICT

From: Cong Wang <cong.wang@...edance.com>

This patchset is the first series of patches separated out from
the original large patchset, to make reviews easier. This patchset
does not add any new feature but merely cleans up the existing
sockmap and skmsg code and refactors it, to prepare for the patches
followed up. This passed all BPF selftests.

The original whole patchset is available on github:
https://github.com/congwang/linux/tree/sockmap

and this patchset is also available on github:
https://github.com/congwang/linux/tree/sockmap1

---
v2: split the original patchset
    compute data_end with bpf_convert_data_end_access()
    get rid of psock->bpf_running
    reduce the scope of CONFIG_BPF_STREAM_PARSER
    do not add CONFIG_BPF_SOCK_MAP

Cong Wang (5):
  bpf: clean up sockmap related Kconfigs
  skmsg: get rid of struct sk_psock_parser
  bpf: compute data_end dynamically with JIT code
  skmsg: use skb ext instead of TCP_SKB_CB
  sock_map: rename skb_parser and skb_verdict
