[PATCH bpf-next] bpf, sockmap: Rename sock_map_get_from_fd to sock_map_prog_attach

From: Xu Kuohai
Date: Wed Aug 30 2023 - 21:44:05 EST


From: Xu Kuohai <xukuohai@xxxxxxxxxx>

What function sock_map_get_from_fd does is to attach a bpf prog to
a sock map, so rename it to sock_map_prog_attach to make it more
readable.
