cachefiles: Register a miscdev and parse commands over it Register a misc device with which to talk to the daemon. The misc device holds a cache set up through it around and closing the device kills the cache. cachefilesd communicates with the kernel by passing it single-line text commands. Parse these and use them to parameterise the cache state. This does not implement the command to actually bring a cache online. That's left for later.
