allocate_cgrp_cset_links(9)

💅 allocate_cgrp_cset_links(9) — Kernel API Manual, bestie edition 🎀

okay so this is a page from the Kernel API Manual (allocate_cgrp_cset_links(9), section 9, kernel-land, very demure very mindful) and honestly? it's a little function with one job and it does it. let's get into it ✨

---

🌸 NAME 🌸

allocate_cgrp_cset_links — literally just allocates cgrp_cset_links. that's it. that's the whole name. iconic minimalism 💅

---

✨ SYNOPSIS ✨

int allocate_cgrp_cset_links (int count , struct list_head *tmp_links );

she takes two args and returns an int. no cap, that's the whole signature 🫶

---

🦋 ARGUMENTS 🦋

• count — the number of links to allocate. like, how many. you tell her how many and she makes that many 🍓
• tmp_links — the list_head that the allocated links get put on. it's the destination. the moment. the main character list ✨

---

👑 DESCRIPTION 👑

Allocate count cgrp_cset_link structures and chain them on tmp_links through ->cset_link. Returns 0 on success or -errno. fr fr that's it — you ask for count of them, she builds count of them, she hooks each one onto tmp_links via its ->cset_link field, and she tells you 0 if it worked or a negative -errno if it didn't 😭💀

lowkey the whole personality of this function: allocate, chain, report. no drama, no surprises, just vibes and structs 🌈
