This is probably the reason for the corruption observed when performing backups based on diff output when fast-diff is active:
https://github.com/elemental-lf/benji/issues/53
While we luckily did not see corruption, we see invalid object maps on a daily basis (probably since we use fstrim) and repair them.

Since we'll stay on Mimic still for our virtualization cluster for a while, I'd love to see this backport happen.
