Yes, i've reserved the code point and superblock fields.  I'm not
going to add INCOMPAT_MMP flag to the supported file until I get and
integrate the patch ext2fs_open() that actually tests for the flag,
though, since that would be a bit silly.

I assume the patch will add a flag to ext2fs_open which skips the MMP
checking.  After all, tune2fs is allowed to make changes to the
superblock while the filesystem is mounted.  So it needs to be able to
open the filesystem read/only even if it is mounted.
