4 | This is a generic journalling layer for block devices. It is |
5 | currently used by the ext3 file system, but it could also be |
6 | used to add journal support to other file systems or block |
7 | devices such as RAID or LVM. |
8 | |
9 | If you are using the ext3 file system, you need to say Y here. |
10 | If you are not using ext3 then you will probably want to say N. |
11 | |
12 | To compile this device as a module, choose M here: the module will be |
13 | called jbd. If you are compiling ext3 into the kernel, you |
14 | cannot compile this code as a module. |

16 | config JBD_DEBUG |
17 | bool "JBD (ext3) debugging support" |
18 | depends on JBD && DEBUG_FS |
19 | help |
20 | If you are using the ext3 journaled file system (or potentially any |
21 | other file system/device using JBD), this option allows you to |
22 | enable debugging output while the system is running, in order to |
23 | help track down any problems you are having. By default the |
24 | debugging output will be turned off. |
25 | |
26 | If you select Y here, then you will be able to turn on debugging |
27 | with "echo N > /sys/kernel/debug/jbd/jbd-debug", where N is a |
28 | number between 1 and 5, the higher the number, the more debugging |
29 | output is generated. To turn debugging off again, do |
30 | "echo 0 > /sys/kernel/debug/jbd/jbd-debug". |
