  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.

  18. help
  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:

  28. Say Y here if you want to be able to handle very large files (bigger
  29. than 2TB), otherwise say N.
  30. If unsure, say Y.
