from what I can tell copy_file_range? does what we need, doesn't it? And it has
support for several filesystems already while IOC_CLONE_RANGE might only be
supported for more filesystems in the future (maybe). David: I can send updated
patch the next days unless we say for some reason that copy_file_range isn't
the way we want to go anyway.
