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.

16config 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".
