Hi Tejun,
Indeed. The point is that these kworker kthreads are easily identifiable.

Personally, I would prefer "kworker/r-%s" and then include the specified workqueue's name e.g. "kworker/r-ext4-rsv-conver". So the rescuer task's name is more consistent with the current naming scheme. I will send a follow up patch.
Kind regards,
