STRUCT MTD_MASTER(9)

🦋 struct mtd_master(9) — like, the actual manual page, bestie 🦋

okay so this is from the Kernel API Manual, and it's about struct mtd_master 💅 buckle up, it's short but it's iconic.

---

✨ NAME ✨

struct mtd_master — the MTD master specific fields, no cap 🔥

---

🌸 SYNOPSIS 🌸

struct mtd_master {
    struct mutex partitions_lock;
    struct mutex chrdev_lock;
    unsigned int suspended : 1;
 };

that's the whole struct, literally right there 👑 (note: chrdev_lock is in the struct fr fr, the page just doesn't say anything about it, and I'm not out here making stuff up 🙈)

---

🎀 Members 🎀

• partitions_lock — the lock that protects accesses to the partition list ✨ and it's not just the master partition list, bestie — it protects all the sub-partitions too. like, every last one. multitasking queen 👑
• suspended — set to 1 when the device is suspended, and 0 otherwise 💤 simple as that, iykyk

---

💜 Description 💜

so this struct gets embedded in mtd_info, and it holds all the master-specific properties/fields 🫶 the master is the root MTD device from the MTD partition point of view — like the main character of the partition situation 💅 periodt.
