kernel - Add refcount_release_wakeup() and refcount_wait()
* refcount_release_wakeup() releases a reference count and wakes up
any waiters on the 1->0 transition.
* refcount_wait() waits for the last reference to go away. When using
this function all release operations on the field must use
refcount_release_wakeup().
