  10          Say Y here if you want to attach large (bigger than 2TB) discs to
  11          your machine, or if you want to have a raid or loopback device
  12          bigger than 2TB.  Otherwise say N.

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

  34          If unsure, say Y.
