unmounting filesystems

[Adam Olsen]

With all this talk about unmounting cds and the like, I wonder, does
the filesystem protocol have a way for for an underlying translator to
request translators ontop of it to shut down?  eg, you run umount
/cdrom, which tells the lowest level translator (libstore or
something?) to try unmounting.  It then asks every translator that has
open ports to it to disconnect, which they'll either do or return
EBUSY.  (typically, passive translators would quit unless something
else has open ports to them, and user programs would return EBUSY,
keeping everything open)
