Is the interface for this going to be ext2meta? Al and sct seemed to
agree that that was the best way act upon the filesystem metadata while
it's online... I'll probably be updating that for 2.5.x VFS changes in
a few weeks, that will provide safe online defrag and a good interface
for other metadata interaction.

It would be nice if this paper were available to everybody, and not
passworded.
