STRUCT SCHED_MM_CID(9)

💖 struct sched_mm_cid — like, the storage unit for per-task MM CID data, bestie 💖

okay so real talk: this is from the Kernel API Manual (that's the manual name, iykyk), and it's genuinely not scary. It's just a little struct that holds MM CID stuff per task. Sit with me, we're gonna get through it together 🫶

✨ NAME ✨

struct sched_mm_cid — literally just storage for per task MM CID data. That's the whole vibe. That's the assignment 💅

---

🌸 SYNOPSIS 🌸

struct sched_mm_cid {
    unsigned int            active;
    unsigned int            cid;
    struct hlist_node       node;
 };

no cap, that's the entire thing. three members. we love a compact icon 👑

🎀 Members 🎀

• active — means the MM CID is active for the task ✨ like yes bestie the CID is live and doing its thing right now.
• cid — the actual CID tied to the task, and here's the tea: it's either permanently assigned or borrowed from the CPU. Two whole situations, one field. versatile queen 🦋
• node — this one's queued in the per MM MMCID list. It's in the group chat. It's on the list. It's booked and busy 📋💅

they all live in the same ✨./include/linux✨ directory together, it's giving found family 🧚

okay bye bestie!! this page ate and left no crumbs 💜 this one's dated October 2026 and comes straight out of ./include/linux — the source/version and date of the page itself, mwah 😘🎀⭐
