1416These files provide a method to access a tasks comm value. It also allows for
1417a task to set its own or one of its thread siblings comm value. The comm value
1418is limited in size compared to the cmdline value, so writing anything longer
1419then the kernel's TASK_COMM_LEN (currently 16 chars) will result in a truncated
1420comm value.
