worker_clr_flags(9)

💅 worker_clr_flags(9) — Kernel API Manual, but make it cute ✨

okay so this is worker_clr_flags(9) from the Kernel API Manual, and it's lowkey one of those tiny housekeeping functions that still matters 💖.

🌸 NAME 🌸

worker_clr_flags — clears worker flags and adjusts nr_running accordingly. That's the whole serve, no cap. 💅

✨ SYNOPSIS ✨

bestie do not freestyle the signature, here it is exactly:

void worker_clr_flags (struct worker *worker , unsigned int flags );

🎀 ARGUMENTS 🎀

• worker — self, literally the worker itself.
• flags — the flags to clear.

🦋 DESCRIPTION 🦋

okay so the vibe is: you clear flags in worker->flags, and you adjust nr_running accordingly. That's it. That's the function. It's giving quiet housekeeping main character energy 💅.

no extra lore here — this page is short and sweet, and we respect that 🍓
