ENUM DAX_WAKE_MODE(9)

✨ enum dax_wake_mode(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil baby of a page — it's literally just an enum and the whole personality is "which waiters do we wake up?" and honestly? iconic 💅 let's go.

---

🌸 NAME 🌸

enum dax_wake_mode — the waitqueue wakeup behaviour situation 💫

---

🦋 SYNOPSIS 🦋

enum dax_wake_mode {
    WAKE_ALL ,
    WAKE_NEXT

};

that's it. that's the whole vibe. two constants, no cap 🫶

---

🎀 Constants 🎀

okay so there's exactly two of them and they're both about who gets woken up, so listen up:

• WAKE_ALL — wakes, like, every single waiter in the waitqueue. all of them. the whole group chat gets the notification 🔥
• WAKE_NEXT — wakes only the first waiter in the waitqueue. just the one. main character energy, everybody else can wait their turn 🙈

no defaults mentioned, no extra lore, that's genuinely the entire enum. don't overthink her 💀
