Calls each function in a notifier chain in turn. The functions run in an atomic context, so they must not block. This routine uses RCU to synchronize with changes to the chain.
If the return value of the notifier can be and'ed with NOTIFY_STOP_MASK then atomic_notifier_call_chain() will return immediately, with the return value of the notifier function which halted execution. Otherwise the return value is the return value of the last notifier function called.

srcu_init_notifier_head - Initialize an SRCU notifier head : Pointer to head of the srcu notifier chain
Unlike other sorts of notifier heads, SRCU notifier heads require dynamic initialization. Be sure to call this routine before calling any of the other SRCU notifier routines for this head.
If an SRCU notifier head is deallocated, it must first be cleaned up by calling srcu_cleanup_notifier_head(). Otherwise the head's per-cpu data (used by the SRCU mechanism) will leak.
