Forget the snippet of code in my original posting as the code in 3.0.12-60
actually looks like this:
if (nodes_added(ls)) {
store_plocks(ls, &sig);
ls->last_plock_sig = sig;
} else {
sig = ls->last_plock_sig;
}
send_plocks_stored(ls, sig);
So sig is never uninitialized. However, the question still remains - node 2
disables plocks for node 1. How are the supposed to be re-enabled?
