description:
For now bitflip the lfs64 magic number.

This will be unflipped when the format is finalized - right now I
still have pending changes to the superblock in mind (to reduce the
number of redundant fields) so anything created now is not future-
proof. However, the code's also nearing being ready for testing; so
I'm doing this before turning it on as a precaution.
