That was caused by this commit:
commit 746ae46c11137ba21f0c0c68f082a9d8c1222c78

drm/sched: Mark scheduler work queues with WQ_MEM_RECLAIM
drm_gpu_scheduler.submit_wq is used to submit jobs, jobs are in the path
of dma-fences, and dma-fences are in the path of reclaim. Mark scheduler
work queue with WQ_MEM_RECLAIM to ensure forward progress during
reclaim; without WQ_MEM_RECLAIM, work queues cannot make forward
progress during reclaim.
However, after further discussion, I think the warning is actually a
false positive. See this discussion:
