What's the best way to do this?  Is it fine to disable caching in all the
network filesystems and then directly remove the fscache and cachefiles
drivers and replace them?  It won't stop the network filesystems actually
working - it'll just mean that they don't do any caching until converted and
have caching reenabled.
