    inet: rename some inet_sock fields · c720c7e8
    Eric Dumazet authored
    In order to have better cache layouts of struct sock (separate zones
    for rx/tx paths), we need this preliminary patch.
    Goal is to transfert fields used at lookup time in the first
    read-mostly cache line (inside struct sock_common) and move sk_refcnt
    to a separate cache line (only written by rx path)
    This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr,
    sport and id fields. This allows a future patch to define these
    fields as macros, like sk_refcnt, without name clashes.
