Prajwal and I discussed if we could deprecate the "stats" functionality of go-criu in favor of the crit package.

This functionality is currently used for --print-stats in checkpointctl (checkpoint-restore/checkpointctl#12) and Podman (containers/podman#12184). However, to be able to update checkpointctl / Podman we might need to first create a new release of go-criu that includes the crit package.

In addition, somewhat similar functionality was introduced in LXD sometime ago that is parsing the stats-dump file to enable pre-copy migration (https://github.com/lxc/lxd/pull/4072). If we could integrate go-criu with LXD it would greatly simplify this part of the code and improve the maintainability.

@checkpoint-restore/go-criu-maintainers What do you think?
