These patches improve blk-mq debugfs support. Thanks, Bart. Changes compared to v1: - Added two patches and replaced patch 1/6 such that debugfs attributes are now unregistered before freeing of a blk-mq queue starts instead of checking the "dead" queue flag. - Changed "rq->cmd_flags ^ op" into "rq->cmd_flags & ~REQ_OP_MASK" as proposed by Omar. - A seq_file pointer is now passed to the new queue_rq callback function instead of a fixed-size char buffer. Bart Van Assche (8): blk-mq: Register /queue/mq after having registered /queue blk-mq: Let blk_mq_debugfs_register() look up the queue name blk-mq: Unregister debugfs attributes earlier blk-mq: Move the "state" debugfs attribute one level down blk-mq: Make blk_flags_show() callers append a newline character blk-mq: Show operation, cmd_flags and rq_flags names blk-mq: Add blk_mq_ops.show_rq() scsi: Implement blk_mq_ops.show_rq() block/blk-mq-debugfs.c | 94 +++++++++++++++++++++++++++++++++++++++++-------- block/blk-mq-sysfs.c | 60 ++++++++++++++++--------------- block/blk-mq.h | 6 ++-- block/blk-sysfs.c | 9 +++-- drivers/scsi/scsi_lib.c | 26 ++++++++++++++ include/linux/blk-mq.h | 6 ++++ 6 files changed, 151 insertions(+), 50 deletions(-) -- 2.12.2
