It is being used by the uretprobe system call on x86 and asm-generic.

Well, the other new syscalls have been in -next for some time, so I
don't really want to move them (and it would make more work for me :-)).

As you say, Linus will just merge these depending on his own ordering.
However, if you switch to 468/568, then he will probably not change it.
I was also hoping that the uretprobe syscall would change to 467 for
the same reason.
