  "message": "block: Expose stacked device queues in sysfs\n\nCurrently stacking devices do not have a queue directory in sysfs.\nHowever, many of the I/O characteristics like sector size, maximum\nrequest size, etc. are queue properties.\n\nThis patch enables the queue directory for MD/DM devices.  The elevator\ncode has been modified to deal with queues that do not have an I/O\nscheduler.\n\nSigned-off-by: Martin K.
