As long as the value fits in the type of u64, it is possible and there
is no technical limitation.
But I am afraid users will be confused in semantics.

For instance, with two RW branches,
- write(2) may return ENOSPC(No space left on device), while df reports
  there left free space.
- on the contrary, df reports the filesystem is full or more than 100%,
  write(2) may success.

I don't think there is a prefect solution for each and every case.
But I have a plan to introduce new mount options,
sum:    total of all branches
wsum:   total of writable branches only
nosum:  first branch only(current behaviour)

Do you think these options are useful?
