Subject: [PATCH bpf-next 0/2] Do not limit cb_flags when creating child sk from listen sk

This set fixes an issue that the bpf_skops_init_child() unnecessarily
limited the child sk from inheriting all bpf_sock_ops_cb_flags
of the listen sk.  It also adds a test to check that.

Martin KaFai Lau (2):
  bpf: tcp: Do not limit cb_flags when creating child sk from listen sk
  bpf: selftest: Ensure the child sk inherited all bpf_sock_ops_cb_flags
