Ocfs2 devel - Apr 2014 - It is maybe a bug, requiring anyone to review it, Thanks.

void o2net_fill_node_map(unsigned long *map, unsigned bytes)
{
struct o2net_sock_container *sc = NULL;
int node, ret;

BUG_ON(bytes < (BITS_TO_LONGS(O2NM_MAX_NODES) * sizeof(unsigned long)));

memset(map, 0, bytes);
for (node = 0; node < O2NM_MAX_NODES; ++node) {
o2net_tx_can_proceed(o2net_nn_from_num(node), &sc, &ret);
if (!ret) {
set_bit(node, map);

             if (sc) {
     sc_put(sc);
             }
}
+ sc = NULL;
}
}
