aa_put_dfa(9)

🦋 aa_put_dfa(9) — Kernel API Manual, bestie edition 🦋

Okay so welcome to the aa_put_dfa(9) page from the Kernel API Manual 💖 this one is short, sweet, and very “handle the refcount, no cap” energy.

---

🌸 NAME 🌸

aa_put_dfa - put a dfa refcount. That's the whole name, and it ate. 💅

---

✨ SYNOPSIS ✨

void aa_put_dfa (struct aa_dfa *dfa );

Copy that exactly, bestie — spacing and all. 🫶

---

🎀 ARGUMENTS 🎀

• dfa — the dfa to put refcount (MAYBE NULL). Yes, it can be NULL, hence the whole “maybe” situation. 🙈

---

💜 DESCRIPTION 💜

Requires: if dfa != NULL that a valid refcount be held.

That's the requirement, periodt. If dfa isn’t NULL, a valid refcount has to be held — that’s the vibe check for this call. 💅✨
