Description

The block device can ask for an fs freeze (dm currently does this). We can do this with rbd when we see that the rbd header updates and a snapshot has been taken. i.e.,

- we get the notifaction
- we reread the header
- we see a new snapshot is there
- we ask the fs to freeze
- we switch to the new snap context
- we ack the notify
