Evan, > With commit 10e5e37581fc ("scsi: ufs: Add clock ungating to a separate > workqueue"), clock gating work was moved to a separate work queue with > WQ_MEM_RECLAIM set, since clock gating could occur from a memory > reclaim context. Unfortunately, clk_gating.gate_work was left queued > via schedule_delayed_work, which is a system workqueue that does not > have WQ_MEM_RECLAIM set. Applied to 4.20/scsi-queue, thanks! -- Martin K.
