STRUCT SCLP_SD_FILE(9)

💅 struct sclp_sd_file(9) — Kernel API Manual, but make it make sense 🎀

okay so bestie, welcome to the Kernel API Manual entry for struct sclp_sd_file — literally the sysfs rep of a Store Data entity ✨

---

🌸 NAME 🌸

struct sclp_sd_file — the sysfs representation of a Store Data entity 🫶

---

✨ SYNOPSIS ✨

struct sclp_sd_file {
    struct kobject kobj;
    struct bin_attribute data_attr;
    struct mutex data_mutex;
    struct sclp_sd_data data;
    u8 di;
 };

no cap, that's the whole struct 👑

---

🦋 Members 🦋

• kobj — the Kobject, its whole little identity 💫
• data_attr — the attribute you use for accessing data contents 📂
• data_mutex — a mutex that serializes access and updates to data (yes, it's giving "one at a time please" energy 🔒)
• data — the data associated with this entity 🍓
• di — the DI value associated with this entity, an u8 icon 💅
