+config LBD
+       bool "Support for Large Block Devices"
+       depends on X86 || (MIPS && 32BIT) || PPC32 || (S390 && !64BIT) || SUPERH || UML
+       help
+         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
+         bigger than 2TB.  Otherwise say N.

+config BLK_DEV_IO_TRACE
+       bool "Support for tracing block io actions"

+       select DEBUG_FS
+       help
+         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:
+
+         git://brick.kernel.dk/data/git/blktrace.git

+config LSF
+       bool "Support for Large Single Files"
+       depends on X86 || (MIPS && 32BIT) || PPC32 || ARCH_S390_31 || SUPERH || UML
+       help
+         Say Y here if you want to be able to handle very large files (bigger
+         than 2TB), otherwise say N.
+
+         If unsure, say Y.
