STRUCT MISC_CG(9)

💅 struct misc_cg(9) — the Kernel API Manual, but make it make sense

okay so bestie, we're looking at struct misc_cg here, and it's literally the Miscellaneous controller's cgroup structure 💖. That's the whole vibe. It lives in the Kernel API Manual and it's a struct, so grab a snack and let's get into it ✨

---

🎀 NAME 🎀

struct misc_cg — the Miscellaneous controller's cgroup structure. that's it, that's the name, no cap 🫶

---

✨ SYNOPSIS ✨

here's the whole thing, exactly as it is, don't come for me about the spacing:

struct misc_cg {
    struct cgroup_subsys_state css;
    struct cgroup_file events_file;
    struct cgroup_file events_local_file;
    struct misc_res res[MISC_CG_RES_TYPES];
 };

like, look at her. iconic. 🌸

🌈 Members 🌈

okay so these are the members, one at a time, no skipping:

• css — the cgroup subsys state object. she's the main character of this struct honestly 👑
• events_file — the handle for the misc resources events file. very "who's keeping receipts" energy 💅
• res — an array of misc resources usage in the cgroup. it's typed MISC_CG_RES_TYPES, so it's giving "one slot per resource type" fr fr 🍓

lowkey note bestie: events_local_file is in the struct up there ☝️ but the manpage doesn't describe it in the Members list, so i'm not gonna invent lore for it. we report, we don't speculate 🙈
