aa_free_data(9)

💖 aa_free_data — free a data blob 💖

okay so bestie, welcome to aa_free_data(9) from the Kernel API Manual — yes we're in kernel land today, and yes you're gonna slay it 🫶

---

✨ NAME ✨

aa_free_data — frees a data blob. that's it. that's the whole job. lowkey iconic for how simple it is 💅

---

🌸 SYNOPSIS 🌸

void aa_free_data (void *ptr , void *arg );

literally just hand it a pointer and it handles the rest, no cap ✨

---

🎀 ARGUMENTS 🎀

• ptr — the data to free. this is the main character of the whole function, give it a little kiss goodbye before it goes 💜
• arg — unused. not me showing up to the function and contributing nothing 😭 it's giving "invited to the group project but did zero slides" energy. it's there, it's ignored, we respect it anyway 🦋
