Okay so welcome to the cleanup_sdt_note_list(9) page from the Kernel API Manual, bestie. This one is lowkey all about freeing the sdt notes' list, and it's giving tidy little cleanup icon energy. ✨

🌸 NAME 🌸

cleanup_sdt_note_list — the function that frees the sdt notes' list. That's the whole vibe. 💅

---

✨ SYNOPSIS ✨

int cleanup_sdt_note_list (struct list_head *sdt_notes );

She takes a struct list_head * named sdt_notes, and she returns an int. Simple, clean, iconic. 🫶

🦋 ARGUMENTS 🦋

• sdt_notes — the sdt notes' list. That's the list being passed in, iykyk. 🎀

---

💖 DESCRIPTION 💖

So what does she actually do? She frees up the SDT notes in sdt_notes, and then she returns the number of SDT notes that got free'd. That's it — no cap, the return value is literally the count of SDT notes free'd. 😭🔥
