      blk-mq: abstract tag allocation out into sbitmap library · 88459642
      Omar Sandoval 提交于
      This is a generally useful data structure, so make it available to
      anyone else who might want to use it. It's also a nice cleanup
      separating the allocation logic from the rest of the tag handling logic.
      
      The code is behind a new Kconfig option, CONFIG_SBITMAP, which is only
      selected by CONFIG_BLOCK for now.
      
      This should be a complete noop functionality-wise.

      blk-mq: account higher order dispatch · 703fd1c0
      Jens Axboe 提交于
      We currently account a '0' dispatch, and anything above that still falls
      below the range set by BLK_MQ_MAX_DISPATCH_ORDER. If we dispatch more,
      we don't account it.
      
      Change the last bucket to be inclusive of anything above the range we
      track, and have the sysfs file reflect that by including a '+' in the
      output:
      
      $ cat /sys/block/nvme0n1/mq/0/dispatched
              0	1006

      blk-mq: introduce blk_mq_delay_kick_requeue_list() · 2849450a
      Mike Snitzer 提交于
      blk_mq_delay_kick_requeue_list() provides the ability to kick the
      q->requeue_list after a specified time.  To do this the request_queue's
      'requeue_work' member was changed to a delayed_work.
      
      blk_mq_delay_kick_requeue_list() allows DM to defer processing requeued
      requests while it doesn't make sense to immediately requeue them
      (e.g. when all paths in a DM multipath have failed).
