Currently the kernel uses open code in multiple places to check if a
task is in the root PID namespace with the kind of format:
if (task_active_pid_ns(current) == &init_pid_ns)
do_something();
This patch creates a new helper function, task_is_in_init_pid_ns(), it
returns true if a passed task is in the root PID namespace, otherwise
returns false. So it will be used to replace open codes.
