aac_cfg_open(9)

💅 aac_cfg_open(9) — like, the Kernel API Manual page bestie 🎀

okay so this one's from the Kernel API Manual, and it's literally the glow-up guide to aac_cfg_open, the function that swings the door open on a configuration file. buckle up, it's short and sweet 🦋

---

✨ NAME ✨

aac_cfg_open — open a configuration file 👑 (yes that's the whole name section, she's lowkey concise)

---

🌸 SYNOPSIS 🌸

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

that's it, that's the signature, copy it exactly pls no editing bestie 💅

---

🎀 ARGUMENTS 🎀

• inode — the inode that's being opened 🫶 like, the actual thing on the filesystem getting the door held open for it
• file — the file handle that's attached 💖 the little handle object riding along with the whole operation

---

⭐ DESCRIPTION ⭐

so here's the tea ☕: this function gets called when the configuration device is opened. it does the needed set up on the handle, and then it returns. that's the whole vibe — set up, return, done, periodt ✨

no cap though, there's a Bugs note and we do NOT skip it:

This needs extending to check that a given adapter is present, so we can support hot plugging, and it also needs to ref count adapters 😭 so yeah — future work, not current behaviour. don't come for me, that's literally what the page says 💀
