This goes back to way before that, that series jut factored out proper
export operations from the two inode or superblock methods we had before
with the rest handled in core code somewhere that made a complete
mess of file systems with 64-bit inode numbers.

Otherwise this looks fine, although splitting the refactoring from
the actual change would make for a much more readable series.
