Thanks. What's your opinion on an SRU to Xenial and/or to Trusty that
allows e2fsprogs to understand the future filesystem feature? Assuming
that no default behaviour would be changed for stable release users,
would this be acceptable to you in principle?
To the rest of the SRU team: any objections to somebody driving this?
I'm not necessarily committing to this wearing my Canonical Server Team
hat, but "enyc" in #ubuntu-devel seems quite interested in driving an
SRU, so it would be useful to get opinions now to avoid any wasted work.
