Hello,

Applied to wq/for-7.0-fixes with the comment updated as below.

Thanks.

if (pwq_activate_first_inactive(pwq, true)) {

- * pwq is unbound. Additional inactive work_items need

- * pwq_tryinc_nr_active() for additional details.
+ * While plugged, queueing skips activation which

+ * inactive, puts the pwq on pending_pwqs.
