    FS-Cache: Add the FS-Cache cache backend API and documentation
    
    Add the API for a generic facility (FS-Cache) by which caches may declare them
    selves open for business, and may obtain work to be done from network
    filesystems.  The header file is included by:
    
    	#include <linux/fscache-cache.h>
    
    Documentation for the API is also added to:
    
    	Documentation/filesystems/caching/backend-api.txt
    
    This API is not usable without the implementation of the utility functions
    which will be added in further patches.
