ocfs2: Switch over to JBD2.
ocfs2 wants JBD2 for many reasons, not the least of which is that JBD is limiting our maximum filesystem size. It's a pretty trivial change. Most functions are just renamed. The only functional change is moving to Jan's inode-based ordered data mode. It's better, too. Because JBD2 reads and writes JBD journals, this is compatible with any existing filesystem. It can even interact with JBD-based ocfs2 as long as the journal is formated for JBD. We provide a compatibility option so that paranoid people can still use JBD for the time being. This will go away shortly. [ Moved call of ocfs2_begin_ordered_truncate() from ocfs2_delete_inode() to ocfs2_truncate_for_delete(). --Mark ] Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
