  "message": "blocK: Restore barrier support for md and probably other virtual devices.\n\nThe next_ordered flag is only meaningful for devices that use __make_request.\nSo move the test against next_ordered out of generic code and in to\n__make_request\n\nSince this test was added, barriers have not worked on md or any\ndevices that don\u0027t use __make_request and so don\u0027t bother to set\nnext_ordered.  (dm explicitly sets something other than\nQUEUE_ORDERED_NONE since\n  commit 99360b4c18f7675b50d283301d46d755affe75fd\nbut notes in the comments that it is otherwise meaningless).\n\nCc: Ken Milmore \u003cken.milmore@googlemail.com\u003e\nCc: stable@kernel.org\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n",
