genwqe_device_remove(9)

✨ genwqe_device_remove 💅

okay bestie, this is the genwqe_device_remove(9) page from the Kernel API Manual. It's short, but highkey important — it's the cleanup moment that removes genwqe's char device, and it has rules about when you can call it. 👑

🎀 NAME 🎀

genwqe_device_remove — Remove genwqe's char device

🦋 SYNOPSIS 🦋

int genwqe_device_remove (struct genwqe_dev *cd );

🌸 ARGUMENTS 🌸

• cd — GenWQE device information. That's the struct genwqe_dev * bestie, the whole device-info situation. 💖

💖 DESCRIPTION 💖

Okay so here's the rule, and it is not a vibe suggestion: this function must be called after the client devices are removed, because it will free the major/minor number range for the genwqe drivers. No cap, that ordering is the whole point. 🫶

Also, this function must be robust enough to be called twice. Yep — twice. It's giving "cleanup queen who can handle a double tap" energy, and that's required, not optional. 💅
