From: Rob Clark <robdclark@xxxxxxxxxxxx> Inspired by https://lore.kernel.org/dri-devel/20200604081224.863494-10-daniel.vetter@xxxxxxxx/ it seemed like a good idea to get rid of memory allocation in job_run() by embedding the hw dma_fence in the job/submit struct. Applies on top of https://patchwork.freedesktop.org/series/93035/ but I can re-work it to swap the order. I think the first patch would be useful to amdgpu and perhaps anyone else embedding the hw_fence in the struct containing drm_sched_job.
