🦋 SYNOPSIS 🦋

int dvb_generic_open (struct inode *inode , struct file *file );

like, that's the whole signature, no cap 👑

🌈 ARGUMENTS 🌈

• inode — it's a pointer to struct inode. that's it, that's the vibe 🫶
• file — a pointer to struct file. iconic, honestly ⭐

---

💖 DESCRIPTION 💖

So what does it actually do? It checks if a DVB devnode is still valid, okay? Then it checks that the permissions are OK. And then it increments the negative use count ✨

That's genuinely the whole thing. short and slay 🔥
