Subject: [PATCH v2 bpf-next 0/2] bpf: Add bpf_sk_storage support to bpf_tcp_ca

This set adds bpf_sk_storage support to bpf_tcp_ca.
That will allow bpf-tcp-cc to share sk's private data with other
bpf_progs and also allow bpf-tcp-cc to use extra private
storage if the existing icsk_ca_priv is not enough.

v2:
- Move the sk_stg_map test immediately after connect() (Yonghong)
- Use global linkage var in bpf_dctcp.c (Yonghong)

Martin KaFai Lau (2):
  bpf: Add bpf_sk_storage support to bpf_tcp_ca
  bpf: Add tests for bpf_sk_storage to bpf_tcp_ca
