rpcrdma_flush_disconnect(9)

💅 rpcrdma_flush_disconnect — the kernel API manual, bestie edition 💅

okay so before we even start, know that you're reading a page from the Kernel API Manual — that's the manual name, i'm folding it in right here at the top so you're never confused about where you are 🫶

---

✨ NAME ✨

rpcrdma_flush_disconnect — literally just "Disconnect on flushed completion". that's the whole vibe. the completion got flushed, we disconnect, periodt 💀

---

🌸 SYNOPSIS 🌸

void rpcrdma_flush_disconnect (struct rpcrdma_xprt *r_xprt , struct
       ib_wc *wc );

yep that's it. void return, two args, no drama ✨ (well, some drama — see the arguments below)

---

🎀 ARGUMENTS 🎀

• r_xprt — the transport to disconnect. this is the thing you're sending to the shadow realm, no cap 🦋
• wc — the work completion entry. it's giving "receipts of what just happened" 👑

---

🦋 DESCRIPTION 🦋

Must be called in process context. that's it, that's the description, and honestly it's kind of iconic that they said exactly one (1) thing — but it's a load-bearing one, so don't get cute and call it from interrupt context, bestie 😭

lowkey reminder bestie: rpcrdma_flush_disconnect lives in ./net/sunrpc/xprtrdma, and calling it anywhere other than process context is not the move 🙈

and that's the page!! stay hydrated, read your manpages, and remember — this gem dropped October 2026 in the ./net/sunrpc/xprtrdma directory, and you're gonna cite rpcrdma_flush_disconnect(9) like the main character you are 👑💖
