STRUCT MISC_RES(9)

✨ struct misc_res(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this little page is all about struct misc_res — literally the per cgroup per misc type resource situation. yes, per cgroup AND per misc type. both. at once. she contains multitudes 🫶

---

🌸 NAME 🌸

struct misc_res — the per-cgroup, per-misc-type resource struct. that's the whole vibe check: one of these lives for each cgroup × each misc type combo 💅

---

🎀 SYNOPSIS 🎀

struct misc_res {
    u64 max;
    atomic64_t watermark;
    atomic64_t usage;
    atomic64_t events;
    atomic64_t events_local;
 };

look at her. five fields, four of them atomic64_t, one humble u64. iconic honestly 🔥

🦋 Members 🦋

here's the group chat roll call, one bullet per member, no gatekeeping:

• max — the maximum limit on the resource. the ceiling. the "you shall not pass" number 👑 it's a u64.
• watermark — the historical maximum usage of the resource. like a screenshot of her peak era, kept forever 📸 it's an atomic64_t.
• usage — the current usage of the resource. the right-now number, the live feed, the main character 💫 it's an atomic64_t.
• events — the number of times the resource limit was exceeded. the counter of chaos. every time somebody pushed past max, this baby noticed 💀 it's an atomic64_t.

ngl, the struct in the synopsis also has events_local in there — this page doesn't give it its own member blurb, so i'm not gonna make one up. she's listed, she's real, that's all we're told 🫶
