int __kprobes __atomic_notifier_call_chain
(struct atomic_notifier_head * nh, unsigned long val, void * v, int nr_to_call, int * nr_calls);
Pointer to head of the atomic notifier chain
Value passed unmodified to notifier function
Pointer passed unmodified to notifier function

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.
