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.

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.

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".
