 /**
  * struct clone_args - arguments for the clone3 syscall
  * @flags:        Flags for the new process as listed above.
  *                All flags are valid except for CSIGNAL and
  *                CLONE_DETACHED.
  * @pidfd:        If CLONE_PIDFD is set, a pidfd will be
  *                returned in this argument.
  * @child_tid:    If CLONE_CHILD_SETTID is set, the TID of the
  *                child process will be returned in the child's
  *                memory.
  * @parent_tid:   If CLONE_PARENT_SETTID is set, the TID of
  *                the child process will be returned in the
  *                parent's memory.
  * @exit_signal:  The exit_signal the parent process will be
  *                sent when the child exits.
  * @stack:        Specify the location of the stack for the
  *                child process.
  *                Note, @stack is expected to point to the
  *                lowest address. The stack direction will be
  *                determined by the kernel and set up
  *                appropriately based on @stack_size.
  * @stack_size:   The size of the stack for the child process.
  * @tls:          If CLONE_SETTLS is set, the tls descriptor
  *                is set to tls.
  * @set_tid:      Pointer to an array of type *pid_t. The size
  *                of the array is defined using @set_tid_size.
  *                This array is used to select PIDs/TIDs for
  *                newly created processes. The first element in
  *                this defines the PID in the most nested PID
  *                namespace. Each additional element in the array
  *                defines the PID in the parent PID namespace of
  *                the original PID namespace. If the array has
  *                less entries than the number of currently
  *                nested PID namespaces only the PIDs in the
  *                corresponding namespaces are set.
  * @set_tid_size: This defines the size of the array referenced
  *                in @set_tid. This cannot be larger than the
  *                kernel's limit of nested PID namespaces.
  * @cgroup:       If CLONE_INTO_CGROUP is specified set this to
  *                a file descriptor for the cgroup.
  *
  * The structure is versioned by size and thus extensible.
  * New struct members must go at the end of the struct and
  * must be properly 64bit aligned.
