DESCRIPTION

25       The process is put to sleep (TASK_UNINTERRUPTIBLE) until the condition
26       evaluates to true. The condition is checked each time the waitqueue wq
27       is woken up.
28
29       wake_up has to be called after changing any variable that could change
30       the result of the wait condition.
31
32       This is supposed to be called while holding the lock. The lock is
33       dropped before going to sleep and is reacquired afterwards.
