Peter Zijlstra 894d1b3db4 locking/mutex: Remove wakeups from under mutex::wait_lock ... In preparation to nest mutex::wait_lock under rq::lock we need to remove wakeups from under it. Do this by utilizing wake_qs to defer the wakeup until after the lock is dropped. [Heavily changed after 55f036ca7e ("locking: WW mutex cleanup") and 08295b3b5b ("locking: Implement an algorithm choice for Wound-Wait mutexes")] [jstultz: rebased to mainline, added extra wake_up_q & init to avoid hangs, similar to Connor's rework of this patch] Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Juri Lelli <juri.lelli@redhat.com> Signed-off-by: John Stultz <jstultz@google.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Metin Kaya <metin.kaya@arm.com> Acked-by: Davidlohr Bueso <dave@stgolabs.net> Tested-by: K Prateek Nayak <kprateek.nayak@amd.com> Tested-by: Metin Kaya <metin.kaya@arm.com> Link: https://lore.kernel.org/r/20241009235352.1614323-2-jstultz@google.com		2024-10-14 12:52:40 +02:00
