What is the advantage, please?
Honestly, I believe that the meaning of
printk("%s\n", task->comm);
is much more clear than using a cryptic %pXYZ modifier:
printk("%pTN\n", task);
The %pXYZ modifiers makes sense only when the formatting of the printed
information needs some processing. But this is a plain string.
IMHO, it is not worth it. In fact, I believe that it is a
counter productive.
