Ubuntu 18.04 may well enable (under review) 64bit,metadata_csum by default, thereby creating ext4 filesystems that are not compatible with e2fsck on Ubuntu-16.04 LTS (or 14.04)?

This creates all sorts of problems for compatibility/portability of filesystems, for e.g.:-
* dual-booting 18.04 and older LTS versions
* "ext4 portable disks" do not work.
* (notice also Ken's hwe-edge/lvm issue above too).

I strongly support that Xenial gets a backport of e2fsprogs-1.43 (as requested) so that this compatibility-annoyance is ameliorated, at least.
Debian have already done this, created a "jessie-backports" e2fsprogs=1.43.3-1~bpo8+1

Hopefully tytso can advise us on the best version of e2fsprogs to backport (18.04 currently has 1.43.9-2).
