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:
25 git://brick.kernel.dk/data/git/blktrace.git
27 config LSF
28 bool "Support for Large Single Files"
29 depends on X86 || (MIPS && 32BIT) || PPC32 || ARCH_S390_31 || SUPERH || UML
30 help
31 Say Y here if you want to be able to handle very large files (bigger
32 than 2TB), otherwise say N.
34 If unsure, say Y.
