I cleaned it up so it looks like this.... and then decided not to apply
it. I don't like this kind of thing being a mount option. Make a new
node type for 'filesystem options'. Make it an RWCOMPAT_COPY node type.
Store the reserved size in it and do it through an ioctl like chattr
does on ext2 -- and make mkfs.jffs2 write it too. 

We'll want compression types stored in that node type too, I suspect.
