  19 /* This file should define the function-like macro of no arguments
  20    ARCH_FORK to an INLINE_SYSCALL invocation of the clone-like system
  21    call, passing the CLONE_CHILD_SETTID and CLONE_CHILD_CLEARTID flags
  22    and &THREAD_SELF->tid as the TID address.

  24    Machines that lack an arch-fork.h header file will hit an #error in
  25    fork.c; this stub file doesn't contain an #error itself mainly for
  26    the transition period of migrating old machine-specific fork.c files
  27    to machine-specific arch-fork.h instead.  */
