STRUCT RNBD_MSG_SESS_INFO(9)

💅 struct rnbd_msg_sess_info(9) — like, the Kernel API Manual but make it make sense 🎀

okay bestie, so picture this: it's the very first thing the client sends to the server. That's it, that's the whole vibe. This struct is the initial session info from client to server — the opening DM, the "hey girlypop" of the RNBD protocol. First impressions, main character energy, slay ✨

🌸 SYNOPSIS 🌸

Like, literally the whole thing:

struct rnbd_msg_sess_info {
    struct rnbd_msg_hdr hdr;
    u8 ver;
 };

Two fields. That's it. Lowkey elegant, highkey iconic 💅

• hdr — the message header, obvs. Every message needs its lil envelope 📬
• ver — the RNBD protocol version. Yes it's a u8, yes it's small, no we're not judging 🥺

🦋 SEE ALSO 🦋

Go read the whole friend group, fr fr — they're all in the kernel file ./drivers/block/rnbd/rnbd-proto.h:

• enum rnbd_msg_type(9)
• struct rnbd_msg_hdr(9)
• struct rnbd_msg_sess_info_rsp(9)
• struct rnbd_msg_open(9)
• struct rnbd_msg_close(9)
• struct rnbd_msg_open_rsp(9)
• struct rnbd_msg_io(9)
• enum rnbd_io_flags(9)

No cap, that's the entire roster 👑

✨ and that's the post ✨ this lil masterpiece lives in ./drivers/block/rnbd, dated October 2026, and it's filed under struct rnbd_msg_sess_info(9) in case you need to find it again. mwah, go forth and read rnbd-proto.h bestie 💖🦋🌸
