And one last note, I also think that the snapshot format change in the

future, when we'll have snpashots with 64bit feature compatible seems
just wrong to me. Adding some features or changing the implementation a
bit is ok, but format change is different. When the code is upstream and
stable it is just wrong.

What can I say, I understand why it looks bad, but is 64bit code
upstream and stable? Hell no! e2fsprogs 64bit is not out yet!
There is no reason to call it 'format change'.
It's going to be a new format used only for 64bit fs, which are not
even out there yet. And when they are finally out there, they won't
have
snapshots until the new format is implemented.

Well, the on-disk format for 64-bit (48-bit?) ext4 is there & fixed; it's
just that there is no released userspace which can properly handle it, right?

I don't anticipate ext4 format changes for >16T, or am I missing something?
