| This is a generic journalling layer for block devices. It is | |
| currently used by the ext3 file system, but it could also be | |
| used to add journal support to other file systems or block | |
| devices such as RAID or LVM. | |
| If you are using the ext3 file system, you need to say Y here. | |
| If you are not using ext3 then you will probably want to say N. | |
| To compile this device as a module, choose M here: the module will be | |
| called jbd. If you are compiling ext3 into the kernel, you | |
| cannot compile this code as a module. | |

| help | |
| If you are using the ext3 journaled file system (or potentially any | |
| other file system/device using JBD), this option allows you to | |
| enable debugging output while the system is running, in order to | |
| help track down any problems you are having. By default the | |
| debugging output will be turned off. | |
| If you select Y here, then you will be able to turn on debugging | |
| with "echo N > /sys/kernel/debug/jbd/jbd-debug", where N is a | |
| number between 1 and 5, the higher the number, the more debugging | |
| output is generated. To turn debugging off again, do | |
| "echo 0 > /sys/kernel/debug/jbd/jbd-debug". |
