need it to check if we can bindmount from external mount note: when migrating from criu with patch to criu without, external mount mapping won't work, we do not support it. v2: s/real_root/ext_real_root/ v4: add comment v5: use ext_key field for mapping, put NO_ROOT_MOUNT in root for old externals for which we do not have it.
