This has been dormant code for many years. Parts of it were removed from the OrangeFS kernel code when it went into mainline. These bits were missed. Now the readahead cache has been resurrected in the OrangeFS userspace portions. It was renamed there, since it doesn't really have anything to do with mmap specifically, so it will be renamed here.
