intel_wakeref_unlock_wait(9)

💅 intel_wakeref_unlock_wait(9) 💅

Okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're fancy here 🎀 — and today's main character is intel_wakeref_unlock_wait, a little function that is literally just here to wait. Iconic behavior, no cap.

---

✨ NAME ✨

intel_wakeref_unlock_wait — wait until the active callback is complete 🫶

---

🌸 SYNOPSIS 🌸

void intel_wakeref_unlock_wait (struct intel_wakeref *wf );

---

🦋 ARGUMENTS 🦋

• wf — the wakeref 💜 (that's it, that's the whole argument, she's lowkey simple like that)

---

⭐ DESCRIPTION ⭐

So what does she do? She waits. For the active callback — the one happening either under wf->mutex or on another CPU — to be complete. ✨

That's the vibe. You call her, she hangs out until the callback is done, and then you can go on with your life. Fr fr, that's the whole thing. 🧚
