like, that's the whole squad and yes i listed every single one because we do NOT skip the boring parts here ma'am ππ
and that's the page!! πβ¨ this cutie lives in ./kernel, the version is October 2026, and the whole thing answers to the name wq_worker_running(9) β ily, go read workqueue.c now, mwah π«Άπ
