The value here must be the same with TASK_COMM_LEN, so I use TASK_COMM_LEN here. But we may also change the code as https://lore.kernel.org/lkml/20211101060419.4682-9-laoar.shao@gmail.com/ if TASK_COMM_LEN is changed, so TASK_COMM_LEN_16 is also okay here. I will change it to TASK_COMM_LEN_16 in the next version.
