Use JBD for compatibility

Linux Kernel Configuration

└─>Use JBD for compatibility
In linux kernel since version 2.6.28 (release Date: 2008-12-24)  
The ocfs2 filesystem now uses JBD2 for its journalling. JBD2
is backwards compatible with JBD. It is safe to say N here.
However, if you really want to use the original JBD, say Y here.
