The following patch enables linux-2.5.2-pre8/fs/intermezzo
to compile, adjusting it to the new kdev_t scheme. I have not
tested it. I only know that it compiles.
In the long term, the Intermezzo team may want to look into
whether kdev_t will reliably not use the most significant bit of
an int (the sign bit), which seems to be the assumption in some of
the error handling code. I don't think that problem is imminent,
however, as I think the currently planned kdev_t expansion is only
to twenty bits.
