__mt_destroy(9)

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

okay so before we even start: yes this is a page from the Kernel API Manual, section 9, and yes it's short. She's a little three-line baddie and honestly? iconic for that. Let's get into it ✨

---

🌸 NAME 🌸

__mt_destroy — walk and free all nodes of a locked maple tree.

that's it. that's the whole job. she walks the tree, she frees the nodes, she leaves. main character energy fr fr 🍓

---

🎀 SYNOPSIS 🎀

void __mt_destroy (struct maple_tree *mt );

literally one function, no return value, takes one pointer. clean. minimal. ate. 💅

---

🦋 ARGUMENTS 🦋

• mt — the maple tree 💖 that's the one you're about to walk through and free node-by-node. she's the whole reason we're here.

---

⚠️ NOTE ⚠️

Does not handle locking. 🫶

and bestie I need you to read that again. this function does not handle locking. it does not take a lock, it does not release a lock, it does not think about locks. the name literally says locked maple tree — so whoever calls this is the one responsible for the locking situation. don't come crying to __mt_destroy about it, she is booked and busy freeing nodes 😭💀

also the kernel file for this whole maple tree situation lives at ./lib/maple_tree.c — that's the source, that's where the magic happens, go look if you're nosy (I'm nosy) 👀
