Couple comments:

1. sk_psock_done_strp() could be static to skmsg.c, as mentioned
   earlier.

2. udp_bpf.c is built when CONFIG_BPF_SYSCALL is enabled, while its API
   declarations in udp.h are guarded on CONFIG_NET_SOCK_MSG.

   This works because BPF_SYSCALL now selects NET_SOCK_MSG if INET, and
   INET has to be enabled when using udp, but seems confusing to me.
