Hi Tejun,
I had a conversation with a colleague of mine. It can be useful to identify
and account for all kernel threads. From the perspective of user-mode, the
name given currently to the rescuer kworker is ambiguous. For instance,
"kworker/u16:9-kcryptd/253:0" is clearly identifiable as an unbound kworker
for the specified workqueue which can have their CPU affinity adjusted as
you mentioned before. I think if we followed the same naming convention
for a rescuer kworker then it would be more consistent. I'll send a patch
so it can be discussed further.
Kind regards,
