	Andrwe Morton posted a fix for the compilation error in
linux-2.5.2-pre8/fs/ext3/super.c.  I have changed his test to
use "!kdev_none()" instead of "!kdev_val()".  It will compile
to the same opcodes, but I think this way is slightly more proper.
It may even make a difference some day if the internal representation
of kdev_val or kdev_none changes in a weird way so that
kdev_val(NODEV) returns non-zero, although I think this is unlikely.
