We can shave off 17 characters by renaming "next_state" to "next", and
replacing its initialization with a standalone assignment.
Most impactful effect [lib/states.c]:
> int
> nbd_internal_enter_STATE_NEWSTYLE_OPT_STRUCTURED_REPLY_RECV_REPLY_PAYLOAD (
> struct nbd_handle *h, bool *blocked
> )
> {
> int r;
> - enum state next_state =
> STATE_NEWSTYLE_OPT_STRUCTURED_REPLY_RECV_REPLY_PAYLOAD;
> + enum state next;
>
> + next = STATE_NEWSTYLE_OPT_STRUCTURED_REPLY_RECV_REPLY_PAYLOAD;
> r = enter_STATE_NEWSTYLE_OPT_STRUCTURED_REPLY_RECV_REPLY_PAYLOAD (
> - h, &next_state, blocked
> + h, &next, blocked
> );
> - if (get_next_state (h) != next_state) {
> + if (get_next_state (h) != next) {
> debug (h, "transition: %s -> %s",
> "NEWSTYLE.OPT_STRUCTURED_REPLY.RECV_REPLY_PAYLOAD",
> - nbd_internal_state_short_string (next_state));
> - set_next_state (h, next_state);
> + nbd_internal_state_short_string (next));
> + set_next_state (h, next);
> }
> return r;
> }
