There's a problem with dependencies between netfslib and fscache as each wants to access some functions of the other. Deal with this by moving fs/fscache/* into fs/netfs/ and renaming those files to begin with "fscache-". For the moment, the moved files are changed as little as possible and an fscache module is still built. A subsequent patch will integrate them.
