Subject: [PATCH 3/4] clone3: align structs and comments
To follow the existing style this commit aligns the comments and
structure settings to have the same look as before. Just with more
spaces.

/**
* 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.
