ENUM DEVICE_LINK_STATE(9)

💅 enum device_link_state(9) — the Kernel API Manual, bestie edition 🎀

okay so this is a page straight out of the Kernel API Manual, and it's all about enum device_link_state, which is literally the vibe-check system for device links. no cap, it's giving "relationship status but for drivers" 🌈

---

✨ NAME ✨

enum device_link_state — Device link states. that's it, that's the whole name section, she's concise 💅

---

🦋 SYNOPSIS 🦋

here's the whole enum, copy it exactly bestie, don't you dare typo it:

enum device_link_state {
    DL_STATE_NONE ,
    DL_STATE_DORMANT ,
    DL_STATE_AVAILABLE ,
    DL_STATE_CONSUMER_PROBE ,
    DL_STATE_ACTIVE ,
    DL_STATE_SUPPLIER_UNBIND

};

---

🌸 Constants 🌸

okay these are the six states and each one is a whole personality, let's go one by one 🫶

• DL_STATE_NONE — The presence of the drivers is not being tracked. nobody's watching, nobody's keeping score, it's giving ghost mode 👻
• DL_STATE_DORMANT — None of the supplier/consumer drivers is present. literally nobody showed up to the party 😭
• DL_STATE_AVAILABLE — The supplier driver is present, but the consumer is not. one half of the duo is here and the other one is on read 💀
• DL_STATE_CONSUMER_PROBE — The consumer is probing (supplier driver present). the consumer is doing its little investigation arc, and the supplier is right there watching 🔥
• DL_STATE_ACTIVE — Both the supplier and consumer drivers are present. both besties showed up, the link is thriving, main character energy fr fr 👑
• DL_STATE_SUPPLIER_UNBIND — The supplier driver is unbinding. the supplier is packing up and heading out, exit music playing 🙈
