From d32d3d0b47f7e34560ae3c55ddfcf68694813501 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 14 Jun 2021 13:17:34 +0200 Subject: nvme-multipath: set QUEUE_FLAG_NOWAIT The nvme multipathing code just dispatches bios to one of the blk-mq based paths and never blocks on its own, so set QUEUE_FLAG_NOWAIT to support REQ_NOWAIT bios.
