For the network namespace work in generic netlink I need to be able to call this function under rcu_read_lock(), otherwise the locking becomes a nightmare and more locks would be needed. Instead, just embed a struct rcu_head (actually a struct listeners_rcu_head that also carries the pointer to the memory block) into the listeners memory so we can use call_rcu() instead of synchronising and then freeing. No rcu_barrier() is needed since this code cannot be modular. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S. Miller <davem@davemloft.net> |
