    blk-mq: create debugfs directory tree · 07e4fead
    Omar Sandoval authored
    In preparation for putting blk-mq debugging information in debugfs,
    create a directory tree mirroring the one in sysfs:
    
        # tree -d /sys/kernel/debug/block
        /sys/kernel/debug/block
        |-- nvme0n1
        |   `-- mq
        |       |-- 0
        |       |   `-- cpu0
        |       |-- 1
        |       |   `-- cpu1
        |       |-- 2
        |       |   `-- cpu2
        |       `-- 3
        |           `-- cpu3
        `-- vda
            `-- mq
                `-- 0
                    |-- cpu0
                    |-- cpu1
                    |-- cpu2
                    `-- cpu3
    
    Also add the scaffolding for the actual files that will go in here,
    either under the hardware queue or software queue directories.
