There are several issues with the way filesystem freeze works in   Linux, among them: there is no check API, which means there is no easy way to know whether a filesystem is frozen or not; it is possible to umount a frozen filesystem despite the fact that there is no API to thaw an unmounted filesystem; it is not possible to freeze multi-device filesystems such as BTRFS; it does not play well with DM snapshot.
