closure_wake_up(9)

💖 closure_wake_up(9) — a Kernel API Manual moment 💖

okay so bestie, welcome to the Kernel API Manual page for closure_wake_up. this is the function that wakes up, like, every single closure chilling on a wait list — and it does it with a memory barrier, so everything stays correct and nothing gets reordered into chaos. ✨

🌸 NAME 🌸

closure_wake_up — wake up all closures on a wait list, with memory barrier. that's it, that's the whole vibe: wake up all closures, on a wait list, with memory barrier. no cap, the memory barrier is part of the package, not an optional little extra. 🫶

---

🎀 SYNOPSIS 🎀

void closure_wake_up (struct closure_waitlist *list );

a void return, so you get nothing back — no error, no count, nothing to check. she just does the thing and dips. 💅

---

🦋 ARGUMENTS 🦋

• list — honestly bestie, the original page literally just says -- undescribed --. 😭 that's it. that's the entire description. so like, i'm not gonna invent one for you and lie to your face — the manpage has left this one as a mystery, and the mystery is the moment. 🙈

fr fr though — if you're staring at the page wondering what list is supposed to be, you're not the problem, the page is. it says the argument exists and then says nothing else. iconic, honestly. 💀
