This series saves task pid and comm in panthor_group and prints task pid and
comm on gpu errors.
v2: save the task info in panthor_group on panthor_group_create, rather than
in panthor_file on panthor_open, because, when the two differ, we are more
interested in the task that created the group.
Chia-I Wu (3):
panthor: set owner field for driver fops
panthor: save task pid and comm in panthor_group
panthor: dump task pid and comm on gpu errors
