* rcu: Update documentation for additional RCU lockdep functionsPaul E. McKenney2011-09-281-3/+21
| | | | | | | | Add documentation for rcu_dereference_bh_check(), rcu_dereference_sched_check(), srcu_dereference_check(), and rcu_dereference_index_check(). Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
* rcu: Not necessary to pass rcu_read_lock_held() to rcu_dereference_protected()Michal Hocko2011-09-281-6/+4
| | | | | | | | | | Since ca5ecddf (rcu: define __rcu address space modifier for sparse) rcu_dereference_check() use rcu_read_lock_held() as a part of condition automatically. Therefore, callers of rcu_dereference_check() no longer need to pass rcu_read_lock_held() to rcu_dereference_check(). Signed-off-by: Michal Hocko <mhocko@suse.cz> Signed-off-by: Paul E.
