STRUCT P9_RDMA_CONTEXT(9)

okay bestie, this is the Kernel API Manual page for struct p9_rdma_context(9) — title and manual name folded in near the top because we're not copying the header line verbatim, we're giving it a lil glow-up 💅✨.

🌸 NAME 🌸

struct p9_rdma_context — Keeps track of in-process WR. That's the whole job, no cap: it's the little record-keeper for an in-process WR, and it's doing it with main character energy 🎀.

✨ SYNOPSIS ✨

Here's the struct exactly as it is, because we do not play with code bestie:

struct p9_rdma_context {
    struct ib_cqe cqe;
    dma_addr_t busa;
    union {
      struct p9_req_t *req;
      struct p9_fcall rc;
    };
 };

• cqe — completion queue entry; it's the completion-queue receipt for your WR, lowkey essential ✨.
• busa — bus address to unmap when the WR completes — you unmap it when the WR completes, no skipping the unmap bestie 🧹💖.
• {unnamed_union} — anonymous; no name, just anonymous union energy 🫥.
• req — keeps track of requests (send) — the send-side tracker 💌.
• rc — Keepts track of replies (receive) — yes, the page literally says Keepts, extra e and all, and we are respecting the lore 😭💅.
