  "message": "dm-snap-persistent: make metadata_wq multithreaded\n\nmetadata_wq serves on-stack work items from chunk_io().  Even if\nmultiple chunk_io() are simultaneously in progress, each is\nindependent and queued only once, so multithreaded workqueue can be\nsafely used.\n\nSwitch metadata_wq to multithread and flush the work item instead of\nthe workqueue in chunk_io().\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Mike Snitzer \u003csnitzer@redhat.com\u003e\nCc: dm-devel@redhat.com\n",
