💅 drbd_request_state(9) — from the Kernel API Manual, bestie

✨ NAME ✨

drbd_request_state — Request a state change 🦋

like literally, you're requesting that a state change happens. that's it, that's the function.

---

🌸 SYNOPSIS 🌸

int drbd_request_state (struct drbd_device *device , union drbd_state
mask , union drbd_state val );

look at her. three args, one int coming back at you. iconic signature, no notes. 💅

---

🎀 ARGUMENTS 🎀

• device — your DRBD device. the main character of this whole operation 🫶
• mask — the mask of state bits you wanna change. tell her which bits, bestie ⭐
• val — the value of the new state bits. this is what you want those bits to actually be ✨

---

👑 DESCRIPTION 👑

so this is the most graceful way of requesting a state change. like, of all the ways to ask, this is the polite one. the well-mannered one. the one with manners. 🌈

and here's the thing — it is verbose. like, quite verbose, fr fr 😭 specifically in the case where the state change is not possible, it will absolutely tell you all about it. no quiet failing here, she's gonna talk.

also important: all of those state changes are globally serialized. every single one. globally. serialized. everybody waits their turn in the group chat 🧚

ngl that "globally serialized" part is the whole personality of this function, so don't forget it 💀
