STRUCT ISER_CTRL(9)

💖 NAME 💖

okay bestie, meet struct iser_ctrl — the iSER header of iSCSI control PDU, straight from the Kernel API Manual. This is the manual page for struct iser_ctrl(9), and we’re doing a full vibe check on every member, no skipping, periodt. 🫶

✨ SYNOPSIS ✨

here’s the exact struct, bestie — keep it cute and keep it literal:

struct iser_ctrl {
    u8 flags;
    u8 rsvd[3];
    __be32 write_stag;
    __be64 write_va;
    __be32 read_stag;
    __be64 read_va;
 };

🎀 Members 🎀

• flags — the opcode and read/write valid bits. lowkey carrying the whole control-PDU vibe. 💅
• rsvd — reserved. not for us, bestie, it’s giving “do not touch.” 🙈
• write_stag — write rkey. slay. ✨
• write_va — write virtual address. iconic. 🌸
• read_stag — read rkey. yes ma’am. 🎀
• read_va — read virtual address. main character energy. 🦋

and that’s the whole page, bestie 🫶 footer vibes: source ./include/scsi, page struct iser_ctrl(9), dated October 2026 — no cap, literally iconic. 💖
