STRUCT NODE_CACHE_INFO(9)

✨ struct node_cache_info(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil struct that lives down in ./drivers/base/node.c — it's the internal bookkeeping for memory node caches, and honestly? it's giving backstage-pass energy 🎀

---

🌸 NAME 🌸

struct node_cache_info — internal tracking for memory node caches 💅

---

🦋 SYNOPSIS 🦋

struct node_cache_info {
    struct device dev;
    struct list_head node;
    struct node_cache_attrs cache_attrs;
 };

like, that's the whole thing. three members. no cap, it's lowkey iconic in its simplicity ✨

---

🎀 Members 🎀

• dev — the device representing the cache level 🫶 (yes, the original spells it "represeting" — we keep the facts, not the typos, but the struct field is exactly dev)
• node — a list element, there so this cache can be tracked in the node 🌸
• cache_attrs — the attributes for this cache level, i.e. all the vibe details 💅
