hl_mmap_mem_buf_destroy(9)

💖 hl_mmap_mem_buf_destroy — destroy the unused buffer 💖

okay so this is a page from the Kernel API Manual, section 9, and it's about one tiny but very important little function bestie, so let's get into it 🫶

---

✨ SYNOPSIS ✨

void hl_mmap_mem_buf_destroy (struct hl_mmap_mem_buf *buf );

that's it. that's the whole signature. no return value, no cap, just vibes and a void 💅

---

🌸 ARGUMENTS 🌸

• buf — the memory manager buffer descriptor 🎀 this is the lil guy you're about to send to the shadow realm.

---

🦋 DESCRIPTION 🦋

okay so listen 👑 — this is an internal function, like not-for-public-consumption, backstage-pass energy. it's used as the final step of buffer release. the way that it's literally the last thing that happens 😭

⚠️ heads up bestie: it shall be invoked only when the buffer is no longer in use — meaning it's already been removed from idr. do not come for this function early, it is NOT ready, it is NOT the moment, it is NOT main character time yet 💀

once you do call it properly, it will call the release callback (if applicable — iykyk, sometimes there just isn't one ✨), and it will free the memory. that's the whole job. clean, iconic, done. periodt. 🔥
