net: macvlan: Use built-in RCU list checking
hlist_for_each_entry_rcu() has built-in RCU and lock checking. Pass cond argument to hlist_for_each_entry_rcu() to silence false lockdep warning when CONFIG_PROVE_RCU_LIST is enabled. Execute as follow: ip link add link eth0 type macvlan mode source macaddr add <MAC-ADDR> The rtnl_lock is held when macvlan_hash_lookup_source() or macvlan_fill_info_macaddr() are called in the non-RCU read side section. So, pass lockdep_rtnl_is_held() to silence false lockdep warning. Fixes: 79cf79ab ("macvlan: add source mode") Signed-off-by: NChuang Wang <nashuiliang@gmail.com> Signed-off-by: NDavid S.
