ENUM GPIO_V2_LINE_CHANGED_TYPE(9)

💅 NAME

Bestie, this is enum gpio_v2_line_changed_type — literally just the set of values that go in &struct gpio_v2_line_changed.event_type. That's the whole assignment. It's giving "small but essential," and honestly? We stan a humble enum. 🎀

This page lives in the Kernel API Manual, in case you were wondering where the vibe check happened. ✨

🦋 SYNOPSIS

enum gpio_v2_line_changed_type {
    GPIO_V2_LINE_CHANGED_REQUESTED ,
    GPIO_V2_LINE_CHANGED_RELEASED ,
    GPIO_V2_LINE_CHANGED_CONFIG

};

Ok so it's three constants, one trailing blank-ish line, and that's it — no cap, that's the entire declaration. Copy it exactly, bestie, commas and all. 🙈

🌸 Constants

• GPIO_V2_LINE_CHANGED_REQUESTED — somebody requested the line. It's claimed now. Iconic behavior. 👑
• GPIO_V2_LINE_CHANGED_RELEASED — the line got released. Free at last, free at last. 🕊️
• GPIO_V2_LINE_CHANGED_CONFIG — the line has been reconfigured. A glow-up, if you will. 💅

Those are the three, fr fr. Nothing hidden, nothing extra. ❤️

✨ And that's the page, bestie! Shoutout to the source at ./include/uapi/linux, dated October 2026, and to the page itself, enum gpio_v2...changed_type(9) — three constants and a dream. Slay, stay hydrated, and may your lines never change unexpectedly. 💜🌈🍓
