svc_rdma_reply_done(9)

✨ svc_rdma_reply_done(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a lil function called svc_rdma_reply_done and honestly? it's giving "i do one thing and i do it correctly." periodt.

---

🌸 NAME 🌸

svc_rdma_reply_done — the Reply chunk Write completion handler 🫶

⭐ SYNOPSIS ⭐

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

like, that's it. that's the whole signature. no cap. 🔥

🎀 ARGUMENTS 🎀

• cq — the controlling Completion Queue 👑 she's the boss of this whole operation
• wc — the Work Completion report 🦋 the receipts, basically

💅 DESCRIPTION 💅

so here's the tea ☕ and it's a short one: pages under I/O are released by a subsequent Send completion.

that's the entire plot, bestie. the I/O pages don't get freed here — they get freed later, when that Send completion comes through. lowkey iconic how the whole function is one sentence of vibes. 😭

ngl this is one of those pages where the description is doing the absolute least, but we respect it — every single word of it is load-bearing 💜
