Hello Jens, This is a short patch series with one patch that exports the queue state and another patch that shows symbolic names for hctx state and flags instead of a numerical bitmask. Please consider these patches for kernel v4.12. Thanks, Bart. Changes compared to v2: - Introduced function blk_flags_show() in patch 1. - Modified error message in patch 1 such that it shows the names of the valid commands. - Added patch "blk-mq: Show symbolic names for hctx state and flags" Changes compared to v1: - Constified blk_queue_flag_name. - Left out QUEUE_FLAG_VIRT because it is a synonym of QUEUE_FLAG_NONROT. - Check array size before reading from blk_queue_flag_name[]. - Add functionality to restart a block layer queue.
