Since task->comm is guaranteed to be NUL-terminated, it can be printed directly. This patch introduces a new vsnprintf format specifier, %pTN, to print a task's name. In this specifier, p represents the task pointer, T stands for "Task," and N denotes "Name." With this abstraction, users no longer need to manually retrieve the task name for printing purposes. In this patchset, all instances of get_task_comm() used for printing the task name have been replaced with the new %pTN specifier. The raw uses of 'xyz->comm' for printouts will be addressed in a subsequent patch.
