svc_rdma_wc_send(9)

✨ svc_rdma_wc_send(9) ✨

okay so this is a page from the Kernel API Manual — yes bestie, kernel manpages are a thing, and this one is lowkey iconic 💅

---

💖 NAME 💖

svc_rdma_wc_send — literally the function that gets invoked by the RDMA provider for each polled Send WC (work completion, iykyk) 🦋

---

🎀 SYNOPSIS 🎀

void svc_rdma_wc_send (struct ib_cq *cq , struct ib_wc *wc );

---

🌸 ARGUMENTS 🌸

• cq — the Completion Queue context, bestie. it's giving "where the completions show up" energy 👑
• wc — the Work Completion object itself, the main character of this whole situation ⭐

---

🦋 DESCRIPTION 🦋

NB: the svc_xprt/svcxprt_rdma is pinned whenever it's possible that the Send completion handler could be running. no cap — that's the whole note 🔥

like, pinned whenever it's possible, not just when it's obviously happening. read it again if you need to, bestie, it's important 🙈
