STRUCT MONGROUP(9)

💖 struct mongroup(9) 💖

okay so this is a page from the Kernel API Manual, section 9 — welcome bestie, we're learning about struct mongroup today and honestly? she's giving "small but mighty" ✨

---

🌸 NAME 🌸

struct mongroup — the struct whose whole job is to store mon group's data in resctrl fs. that's it. that's her purpose. iconic.

---

🎀 SYNOPSIS 🎀

here's the whole vibe, laid out for u:

struct mongroup {
    struct kernfs_node      *mon_data_kn;
    struct rdtgroup         *parent;
    struct list_head        crdtgrp_list;
    u32 rmid;
 };

no cap, that's the entire thing. four members. she's compact 💅

---

🦋 Members 🦋

lowkey the important part, so pay attention bestie:

• mon_data_kn — the kernfs node for the mon_data directory 🗂️
• parent — the parent rdtgrp 🫶
• crdtgrp_list — the child rdtgroup node list 🌈
• rmid — the rmid for this rdtgroup 🔥

---
