Sorry it's just to check with you before sending a useless series.
Sounds good this, for the 2 system_percpu_wq commit logs?
I don't think there is more to add here, because it is a wq rename.


This patch continues the effort to refactor worqueue APIs, which has begun
with the change introducing new workqueues and a new alloc_workqueue flag:

commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")

For more details see the Link tag below. Replace system_wq with
system_percpu_wq, keeping the same behavior.


Thanks!
