-
-In 7675104990ed ("sched: Implement lockless wake-queues") we gained
-lockless wake-queues. -RT managed to lockup itself with those. There
-could be multiple attempts for task X to enqueue it for a wakeup
-_even_ if task X is already running.
-The reason is that task X could be runnable but not yet on CPU. The the
-task performing the wakeup did not leave the CPU it could performe
-multiple wakeups.
-With the proper timming task X could be running and enqueued for a
-wakeup. If this happens while X is performing a fork() then its its
-child will have a !NULL `wake_q` member copied.
-This is not a problem as long as the child task does not participate in
-lockless wakeups :)
