Hello, Aaron.
Aaron Tomlin (3): workqueue: Add workqueue_cpu_intensive tracepoint workqueue: Add workqueue_mayday and workqueue_rescued tracepoints workqueue: Add workqueue_bh_budget_yield tracepoint
Applied 1-3 to wq/for-7.4 with the mayday interval references removed and "executing CPU" changed to "pool CPU" in the BH tracepoint description. The comment adjustment is below. Thanks. -- tejun
