wake_up_atomic_t9
Wake up a waiter on a atomic_t
Usage
void wake_up_atomic_t(atomic_t * p);
Arguments
p
The atomic_t being waited on, a kernel virtual address
Overview
Wake up anyone waiting for the atomic_t to go to zero.
Abuse the bit-waker function and its waitqueue hash table set (the atomic_t check is done by the waiter's wake function, not the by the waker itself).
