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

Applied to 4.20/scsi-queue, thanks!
