| #XXX - it makes sense to enable this only for 32-bit subarch's, not for x86_64 |
| #for instance. |
| 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 RELAY |
| 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: |
