vringh_notify_enable_user(9)

💅 NAME 💅

Okay bestie, welcome to vringh_notify_enable_user(9) from the Kernel API Manual — and the vibe is literally right there in the name: vringh_notify_enable_user — we want to know if something changes. That’s the whole assignment. Periodt. ✨

🌸 SYNOPSIS 🌸

Here’s the signature, copy it exactly:

bool vringh_notify_enable_user (struct vringh *vrh );

🎀 ARGUMENTS 🎀

• vrh — the vring. That’s it. That’s the argument. Main character struct energy. 💅

🦋 DESCRIPTION 🦋

Okay so the tea is: this function always enables notifications. Like, it is not asking permission — notifications are getting enabled. But it returns false if there are now more buffers available in the vring. So when you call it, keep an eye on that return value, because false is lowkey telling you there are now more buffers available in the vring. No cap. 👀
