mei_cl_wake_all(9)

💅 mei_cl_wake_all(9) — the Kernel API Manual, but make it make sense

okay so bestie, we're in mei_cl_wake_all(9) territory today — yes, the nine is giving "kernel internal, do not @ me". It lives in the Kernel API Manual, and it's genuinely iconic.

✨ NAME ✨

mei_cl_wake_all — wake up readers, writers and event waiters so they can be interrupted 🫶

Like, it's literally the "hey bestie, wake up, something's happening" function. Everyone waiting on this client gets nudged so an interrupt can actually land. no cap.

---

🦋 SYNOPSIS 🦋

void mei_cl_wake_all (struct mei_cl *cl );

that's it. that's the whole signature. void in, void out, chaos in between 💀
