Say Y here if you want to attach large (bigger than 2TB) discs to

your machine, or if you want to have a raid or loopback device

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

When CONFIG_LBD is disabled, say Y here if you want to

handle large file(bigger than 2TB), otherwise say N.
|
|
When CONFIG_LBD is enabled, Y is set automatically.
