Subject: jbd: only create debugfs entries if cache initialisation is successful
From: "Duane Griffin" <duaneg@xxxxxxxxx>
JBD debugfs entries should only be created if cache initialisation is
successful. At the moment they are being created unconditionally which will
leave them dangling if cache (and hence module) initialisation fails.
