ITYM "can be papered over by..."; *IF* fill_super() is the only place where
these are taken in such order, this is strictly worse than the current
situation - you are taking a false positive from lockdep (fill_super is
not going to have any other threads accessing the same fs instance) and
adding random failures and syslog spew where none existed.

NAK in that form; it _may_ serve as a stopgap if fill_super is not
the only place where we do it in such order, but even then we need
to deal with the problem properly.
