[PATCH] SUNRPC: drop stale comment in svc_setup_socket()

[PATCH] SUNRPC: drop stale comment in svc_setup_socket()

[Stefan Hajnoczi]

Since 9660439861aa8dbd5e2b8087f33e20760c2c9afc ("svcrpc: take advantage
of tcp autotuning") the svc_setup_socket() function does set the send
and receive buffer sizes so the comment is out-of-date:

  /* initialise setting must have enough space to
   * receive and respond to one request.
   */
  svc_sock_setbufsize(svsk->sk_sock, 4 * serv->sv_max_mesg,
                                     4 * serv->sv_max_mesg);

Hm, looks like it did it before too, just in svc_tcp_init instead.
Anyway, agreed that the comment doesn't look like much help, applying
your patch with a shorter changelog--thanks.
