STRUCT RTRS_SG_DESC(9)

🦋 NAME 🦋

okay so struct rtrs_sg_desc(9) is literally the RDMA-Buffer entry description from the Kernel API Manual 💅 — a tiny but iconic struct, and yes, she ate.

✨ SYNOPSIS ✨

here's the whole look, bestie — no cap, this is the exact shape:

       struct rtrs_sg_desc {
           __le64 addr;
           __le32 key;
           __le32 len;
        };

💖 Members 💖

• addr — Address of RDMA destination buffer</p> — where the RDMA destination buffer lives, fr fr.
• key — Authorization rkey to write to the buffer — the rkey that authorizes writing to the buffer, iykyk.
• len — Size of the buffer — how big the buffer is, periodt.
