Why introduce a new syscall instead of extending sys_splice?
Personally, I think it's ugly to have different operations use the same
syscall just because their arguments match.
I agree with Zach - having a system call called "splice" do copy offloads is not
intuitive.
This is a very reasonable name for something that battled its way through
several standards bodies (for NFS and SCSI :)), so we should give it a
reasonable name
thanks!

But that preference aside, sure, if the consensus is that we'd rather
use the splice() entry point then I can duck tape the pieces together to
make it work.
If the user doesn't need a out offset, then sendfile() should also be
able to transparently utilize COPY/CLONE_RANGE, too.
Perhaps, yeah.
