Hello Jens, While analyzing the mq-deadline behavior for ZBC drives together with Damien we noticed the following: - That the request queue attribute methods are not contiguous in blk-mq-debugfs.c. - That the information about which zones are locked is not yet available in debugfs. Hence this patch series. Please consider this patch series for kernel v4.17. Thanks, Bart.
