v3: drop sk_psock_get_checked()
    reuse tcp_bpf_sock_is_readable()

v2: rename and reuse ->stream_memory_read()
    fix a compile error in sk_psock_get_checked()

Cong Wang (3):
  net: rename ->stream_memory_read to ->sock_is_readable
  skmsg: extract and reuse sk_msg_is_readable()
  net: implement ->sock_is_readable() for UDP and AF_UNIX

Yucong Sun (1):
  selftests/bpf: use recv_timeout() instead of retries
