ENUM RTRS_MSG_TYPES(9)

💖 enum rtrs_msg_types(9) 💖

okay so bestie, we're diving into the Kernel API Manual for enum rtrs_msg_types — section 9, obvs — and it's literally all about the message types that RTRS uses to talk. also check rtrs/README if you want the full lore, iykyk. 🫶

✨ SYNOPSIS ✨

enum rtrs_msg_types {
    RTRS_MSG_INFO_REQ ,
    RTRS_MSG_INFO_RSP ,
    RTRS_MSG_WRITE ,
    RTRS_MSG_READ ,
    RTRS_MSG_RKEY_RSP

};

🌸 Constants 🌸

like, here's the whole cast of characters — main character energy only:

• RTRS_MSG_INFO_REQ — client is like "hey server, can u send over some extra info pls??" — it's giving additional info request, fr. 🙈
• RTRS_MSG_INFO_RSP — server's turn to respond to the client with that additional info. slay. 💅
• RTRS_MSG_WRITE — client literally writes data to the server via RDMA. iconic behavior. 🔥
• RTRS_MSG_READ — client is requesting a data transfer from the server, no cap. 📥
• RTRS_MSG_RKEY_RSP — server sends back a refreshed rkey for the rbuf. obsessed with this whole handshake tbh. ✨

kisses, ur favorite kernel girlie — this page came straight from ./drivers/infiniband/ulp/rtrs in the Kernel API Manual, October 2026 edition. go forth and understand those message types, queen. 👑💜
