Hmm, this may be a kernel bug also, in a way. I don't know if ext2
allows you to set attributes on char/block special files, but if it
does, then the "immutable" attribute should _probably_ apply to
changing the device inode, rather than writing to the device itself.
In any case, it is also a bad thing to leave garbage in unused parts of
on-disk data structs for just this reason, so mkreiserfs should zero
everything that is unused inside allocated structs (and the kernel too,
because reiserfs allocates inode tables dynamically, right?).
