It should also be noted that if you are using an enterprise linux
distro, something like a "Linux 3.10" or an "e2fsprogs 1.42.9" from an
enterprise linux has so many backports that it's going to be quite
different from an upstream version. As a result, you're probably
going to be better off seeking help from the enterprise linux's
support desk, since they will be set up to help you much better than
usptream developers.
Also, there is a big difference between what an enterprise linux might
support and a community distro. For example, even though Fedora has
defaulted to btrfs, Red Hat Enterprise Linux has not decided to
support btrfs. It was a techniolgy preview in RHEL 6 and 7, but it
was fully removed in RHEL 8.
So again, if you are using an Enterprise Linux distribution, you
should really ask their support folks so you can get their advice, and
find out what they will actually support.
Cheers,
