In proc_pid_status, task_cpus_allowed is used to show cpus_allowed, similar to that, task_mems_allowed is more specific to show mems_allowed. Also cpuset_task_status_allowed is used to dispaly memory status in '/proc/<pid>/status' and isn't used in other files, so keep it in the fs/proc/array.c. Thanks, Haifeng.
