STRUCT UTP_UPIU_REQ(9)

💖 struct utp_upiu_req — the general upiu request structure 💖

okay so bestie, this is manual page 9 from the Kernel API Manual for struct utp_upiu_req. It’s the general upiu request structure, and we’re about to give every single member a full vibe check. no skipping, no cap. 💅✨

🌸 NAME 🌸

struct utp_upiu_req — general upiu request structure. 🫶

🦋 SYNOPSIS 🦋

the way this struct is laid out is iconic, and every character stays exactly where it belongs:

       struct utp_upiu_req {
           struct utp_upiu_header header;
           union {
             struct utp_upiu_cmd             sc;
             struct utp_upiu_query           qr;
             struct utp_upiu_query           uc;
           };
        };

💅 Members 💅

okay these members are giving main character energy, and every one of them matters:

• header — UPIU header structure, DW-0 to DW-2. 👑
• {unnamed_union} — anonymous. literally an anonymous union, bestie. 🫶
• sc — fields structure for scsi command, DW-3 to DW-7. 🔥
• qr — fields structure for query request, DW-3 to DW-7. 🌈
• uc — use utp_upiu_query to host the 4 dwords of uic command. 💜
