/**

 * struct clone_args - arguments for the clone3 syscall

 *                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.

 *

 * The structure is versioned by size and thus extensible.

 * New struct members must go at the end of the struct and

	__aligned_u64 stack;

	__aligned_u64 stack_size;

	__aligned_u64 tls;

	__aligned_u64 set_tid;

	__aligned_u64 set_tid_size;
