- help
- 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.
- config JBD_DEBUG
- bool "JBD (ext3) debugging support"
- depends on JBD && DEBUG_FS
- 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".
