This function returns immediately on error if the caller provided errp.
It continues if the caller did not provide errp.
I'm not sure if you wanted this difference in behavior.
The following always returns immediately on error, even when the caller
did not provide errp:
void replication_start_all(ReplicationMode mode, Error **errp)
{
ReplicationState *rs, *next;
Error *local_err = NULL;
QLIST_FOREACH_SAFE(rs, &replication_states, node, next) {
if (rs->ops && rs->ops->start) {
rs->ops->start(rs, mode, &local_err);
}
if (local_err) {
error_propagate(errp, local_err);
return;
}
