| 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". |
