css_get_many(9)

💖 css_get_many(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, this is css_get_many(9), and it's literally the group-chat equivalent of grabbing a whole handful of references at once. no cap. 🫶

---

✨ NAME ✨

css_get_many — obtain references on the specified css ✨ (yes, plural, many, a whole squad of them 💅)

---

🦋 SYNOPSIS 🦋

CGROUP_REF_FN_ATTRS void css_get_many (struct cgroup_subsys_state *css ,
unsigned int n );

like, that's the whole signature. iconic. no notes. 👑

---

🎀 ARGUMENTS 🎀

• css — target css 🎯 the actual thing you're grabbing refs on, the main character of this function ngl
• n — number of references to get 🔢 like how many you want, times n, that many, fr fr

---

🌸 DESCRIPTION 🌸

okay so here's the tea: the caller must already have a reference. 💀

that's it. that's the whole description. you gotta already be holding one before you call this — it's giving "you need experience to get the job" energy but for kernel refcounting 😭. don't come in with zero refs and expect css_get_many to fix your life, because that is not what it does.
