The configuration item CONFIG_JBD:

Help text

This is a generic journalling layer for block devices. It is currently used by the ext3 and OCFS2 file systems, 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 or OCFS2 file systems, you need to say Y here. If you are not using ext3 OCFS2 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 or OCFS2 into the kernel, you cannot compile this code as a module.
