Hi Jens, unfortunately, the patch "block, bfq: decrease burst size when queues in burst exit", queued for 4.15 [1] introduces a bug, described in detail in the commit message of this patch. If triggered, this bug may cause loss of control on I/O-request service order.
Please queue this fix right after the patch introducing the bug.
Thanks, Paolo
