frwr_wc_localinv(9)

💅 frwr_wc_localinv — Kernel API Manual, bestie edition 🎀

okay so real quick, the manual name is frwr_wc_localinv(9) and it lives in the Kernel API Manual, and honestly? it's giving "tiny little callback with main character energy" ✨

---

🌸 NAME 🌸

frwr_wc_localinv — bestie, this one gets invoked by the RDMA provider when there's a LOCAL_INV WC 😭 and yes we will explain what that means (sort of — the manpage keeps it lowkey mysterious, so we're not gonna make stuff up 💀)

---

✨ SYNOPSIS ✨

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

look at her. two args. returns void. no notes, she's perfect 🫶

---

🦋 ARGUMENTS 🦋

• cq — the completion queue 💫 that's it, that's the whole description, the original said it and we're not about to invent lore.
• wc — the WCE for a completed LocalInv WR 🔥 (a work completion entry, for the record — and it's specifically the one for a completed LocalInv work request, no cap)

ngl bestie these are the shortest argument descriptions ever, but we are not padding them out with fake facts. the manpage said what it said 💅
