The wire protocol changes for using 64-bit-sized volumes have already
been listed[1], if I'm not mistaken (or at least some of them, if I
missed any). It's not an internet draft, but it does have the relevant
fields, if you wanted to work from there.

I don't believe those changes are necessary to use "large" volumes,
though; they only need to exist to get correct reporting on volume
usage, and for setting volume quotas above the 31-bit mark.

[1] The ones under the sections '64-bit unsigned values for volume
quotas' and '64-bit unsigned values for volume blocks in use, partition
blocks in use, and maximum partition blocks' in:
