Unless .probe_type = PROBE_PREFER_ASYNCHRONOUS is set or a module is loaded using with the "async_probe=1" parameter. So I believe the wait queue won't be needed. The only DRM driver that forces an async probe is drivers/gpu/drm/hyperv/hyperv_drm_drv.c AFAICT. So I would drop this patch from the set for now. -- Best regards, Javier Martinez Canillas Core Platforms Red Hat
