The patch itself looks fine to me, and is a good idea.  I recently saw a
confused user on another fs where successful mount messages were
followed by failure mount messages with no indication of which fs had
the trouble...

There probably are more spots in extX which could use this treatment...
should we maybe just be using ext3_warning in more places, which
automatically prints the sb, function name, etc?
