Except we can't use clone2() because it conflicts on ia64.  Care to propose
a name you would prefer?

Also I was a bit suprised to discover there are plenty of examples where this
convention has not been followed: vm86, lseek64, and mmap2 to name a few. In
fact, of the 46 __NR_foo[[:digit:]]+, 36 break this convention on x86-32.
