Subject: e2fsprogs: Richacl support

Hello,

could the richacl feature flag please be added to e2fsprogs so that we
won't end up with incompatible file systems?

  https://github.com/andreas-gruenbacher/e2fsprogs

Also, should this really be an incompatible feature flag? With a
read-only compatibility flag, mounting a richacl filesystem on a
kernel without richacl support would work but it's not safe --- it
could grant unwanted access to files. (The same applies to the xfs
support, etc.)

Thanks,
Andreas
