Not to be pedantic, but should this allow "ignore_errors", since it will
presumably ignore more than one error. If already using "ignore_error"
in the field you could accept both for some time until able to change over,
as we've done with "ea_inode" vs. "large_xattr" in the Lustre e2fsprogs
for years.

This should go after the "---" so that it isn't in the final commit message.

"e2image"

Ted could fix this in the final commit

Hello.

Andreas, thank you for the review.
It looks like remarks don’t require v6 and can be fixed during a merge.

Does anybody has other any objections/ideas?

Thanks.
Artem Blagodarenko.
