      drm: Remove utterly bogus preempt_disable() sections · d53dab3a
      Thomas Gleixner authored
      commit 27641c3f (drm/vblank: Add support for precise vblank
      timestamping) adds preempt_disable()/enable() around a spin locked
      section with the comments:
      
       * Disable preemption, so vblank_time_lock is held as short as
       * possible, even under a kernel with PREEMPT_RT patches.
      
      /* Disable preemption while holding vblank_time_lock. Do
       * it explicitely to guard against PREEMPT_RT kernel.
      
      Just that this has never been tested on a RT kernel which would have
      granted that nonsense with a might_sleep() warning because
      dev->vblank_time_lock is converted to a "sleeping" spinlock on RT.
      
      So this is activly wrong on RT and superflous on mainline. Remove it.
