macio_release_dev(9)

🦋 macio_release_dev(9) 🦋

okay bestie, welcome to the Kernel API Manual — today's main character is macio_release_dev(9), and honestly? She's a cleanup girlie with a very specific job. Let's get into it 💅✨

🌸 NAME 🌸

macio_release_dev — frees a macio device structure when all users of it are finished. That's the whole vibe: everybody done? structure gets freed. periodt 💖

✨ SYNOPSIS ✨

void macio_release_dev (struct device *dev );

one function, one argument, no cap 🫶

🎀 ARGUMENTS 🎀

• dev — the device that's been disconnected. Like, it's already been taken out of the group chat 💅

💖 DESCRIPTION 💖

okay so the tea is: this function will be called only by the device core — not by your random driver bestie — and only when all users of this macio device are done. Slay, but here's the plot twist: currently that means never, because we don't hot remove any macio device yet. Ngl, it's giving "theoretically ready." That said, it will happen with mediabay based devices in a later implementation, so the future is coming ✨🦋
