When hlist_for_each_entry_continue_rcu_bh() gets "next" pointer of hlist_node structure through rcu_dereference_bh(), sparse warning appears as the "next" pointer is not annotated as __rcu. So if the "next" pointer is accessed with hlist_next_rcu() macro, the __rcu annotation will be added to the pointer. As a consequence, sparse warning is eliminated too.
The similar errors also appear in hlist_for_each_entry_continue_rcu() and hlist_for_each_entry_from_rcu(). In this version, CC more people like Paul E. McKenney and lkml mail list.
