      drm/sched: Avoid lockdep spalt on killing a processes · 542cff78
      Andrey Grodzovsky authored
      Probelm:
      Singlaning one sched fence from within another's sched
      fence singal callback generates lockdep splat because
      the both have same lockdep class of their fence->lock
      
      Fix:
      Fix bellow stack by rescheduling to irq work of
      signaling and killing of jobs that left when entity is killed.
