Overview
Control will return to the caller some time after a full rcu_bh grace period has elapsed, in other words after all currently executing rcu_bh read-side critical sections have completed. RCU read-side critical sections are delimited by rcu_read_lock_bh and rcu_read_unlock_bh, and may be nested.
See the description of synchronize_sched for more detailed information on memory ordering guarantees.
