Keep in mind that the way to get the most out of this meeting
is for the fs people to have topics of the form "we'd really
like to do X, can we get some help from the VM"? Or vice versa

That said, we can talk about whatever interests the group on
the day. And that could definitely include issues common to
different filesystems.
