Hmm, I'm not seeing this mkfs.ext4 failure using 1.47.0.  I have two
cherry-picks on top of 1.47, but neither relate to mkfs.ext4:

  24a11cc371a4 ("e2fsck: Suppress "orphan file is clean" message in preen mode")

and

  8798bbb81687 ("e2fsck: fix handling of a invalid symlink in an inline_data directory")

See:

Can you confirm what version of e2fsprogs you are using?  Is it
exactly 1.47.0, or do you have some additional commits (either from
the upstream master or maint branches) applied?

That's correct.
