Okay so bestie, welcome to the group chat for __virtio_clear_bit — a tiny little helper that clears feature bits, and it's specifically for use by transports. That's the whole vibe. It's a behind-the-scenes king, not a main character you call from your random driver, iykyk. 👑

🌸 NAME 🌸

__virtio_clear_bit — helper to clear feature bits. For use by transports. periodt. 🎀

🦋 SYNOPSIS 🦋

void __virtio_clear_bit (struct virtio_device *vdev , unsigned int fbit );

No return value, she's a void, she just does the thing and leaves. 💅

✨ ARGUMENTS ✨

• vdev — the device 🫶 like, the actual struct virtio_device you're working on, the whole point of the operation
• fbit — the feature bit 🔥 the specific one you want cleared, an unsigned int, no cap

That's it. Two args. Lowkey elegant, highkey essential. 💖
