Enable smart wake ups with wake_up_info() patch introduces a new wake up function wake_up_info() that enables the caller to pass additional information to the woke up tasks. The information is passed to the callback function registered inside the wait structure.
The Story
The current (2.6.0) Linux kernel does not allow the task that wakes up a wait queue, to pass information about the cause of the wake up and this forces the freshly wake up tasks to perform additional steps to query such information. This is time consuming and not efficent.
