  11           your machine, or if you want to have a raid or loopback device
  12           bigger than 2TB.  Otherwise say N.

  19           Say Y here, if you want to be able to trace the block layer actions
  20           on a given queue. Tracing allows you to see any traffic happening
  21           on a block device queue. For more information (and the user space
  22           support tools needed), fetch the blktrace app from:
