Hello Hannes, Such functionality will be added to the blk-mq core as part of the initiative to add blk-mq I/O scheduling support. One implementation has been proposed by Jens (http://git.kernel.dk/cgit/linux-block/log/?h=blk-mq-sched) and another implementation has been proposed by myself (https://lkml.org/lkm l/2016/12/22/322).
