Subject: [PATCH RFC 2/2] fs/proc: Pass 'task->full_name' via 'proc_task_name()'

Now that we have the get_task_full_name() implementation which allows
the dynamically allocated and filled in task's full name to be passed
to interested users, use it in proc_task_name() by default for
task names so that user-land can see them through appropriate tools
(such as 'ps').
