The following patches fix up the garbage collection for the knfsd file cache, to make the behaviour under load be more predictable. It also separates out the garbage collectors for knfsd instances running under different containers to ensure that a close() or fput() of a file in one container that hangs or is slow won't gum up the system for all the other containers.
