I've changed the type of write_super_lockfs and unlockfs from "void" to
"int" so that they can return an error.

Returning an error from the freeze operation makes sense, but for the
unfreeze I don't see the point. You must however change all existing
instances to actually return a value (even if it's always 0 for now)
to avoid breaking git bisect.

I thought unlockfs should return an error because ext3_unlockfs()
might cause I/O error in writing a super block.
But it is an internal error and the unfreezing succeeds.
So I will consider returning 0.

If you touch all instances anyway, it would be nice to rename them
to freeze / unfreze as the current names are more confusing.

I will consider renaming.

Cheers, Takashi
