STRUCT UIC_COMMAND(9)

✨ struct uic_command(9) ✨

okay bestie, welcome to the kernel API manual page for struct uic_command 🫶 this one lives in ./include/ufs and honestly? it's giving "tiny struct, big responsibilities." it's the UIC command structure — no cap 💅

---

🌸 NAME 🌸

struct uic_command — the UIC command structure, periodt 💖

---

🦋 SYNOPSIS 🦋

struct uic_command {
    const u32 command;
    const u32 argument1;
    u32 argument2;
    u32 argument3;
    bool cmd_active;
    struct completion done;
 };

like, look at her. six members. absolutely iconic 👑

---

🎀 Members 🎀

• command — the UIC command itself, and it's const u32 so bestie is NOT changing her mind 🔒
• argument1 — UIC command argument 1, also const u32, also not budging ✨
• argument2 — UIC command argument 2, this one's a regular u32 so she's flexible 💁‍♀️
• argument3 — UIC command argument 3, u32 again, slay 🌸
• cmd_active — a bool that tells you if the UIC command is outstanding 👀 like, is she still out there? yes ma'am she is
• done — a struct completion for UIC command completion 🎀 the little "we're done here" moment, we love a finish line

ngl bestie, this is the entire page — no hidden warnings, no sneaky exit statuses, no environment variables. just the struct and her friends. keep every member exactly as written and you're golden 🧚
