notifier_call_chain — Call functions in a notifier chain
int __kprobes notifier_call_chain ( | struct notifier_block ** | n, |
| unsigned long | val, | |
| void * | v); |
nPointer to root pointer of notifier chain
valValue passed unmodified to notifier function
vPointer passed unmodified to notifier function
Calls each function in a notifier chain in turn.
If the return value of the notifier can be and'd
with NOTIFY_STOP_MASK, then 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.
