xprt_rdma_inject_disconnect(9)

💅 xprt_rdma_inject_disconnect(9) — like, the kernel API manual page, bestie 🎀

okay so this is a page straight out of the Kernel API Manual, and honestly? it's a whole vibe. it's short, it's spicy, it messes with your network connection on purpose. let's get into it ✨

---

🌸 NAME 🌸

xprt_rdma_inject_disconnect — inject a connection fault 💀

yes. that's the whole job. she injects. a fault. into a connection. iconic, honestly.

---

🦋 SYNOPSIS 🦋

void xprt_rdma_inject_disconnect (struct rpc_xprt *xprt );

that's it. that's the whole signature. void in, void out, one pointer in between. slay.

---

💖 ARGUMENTS 💖

• xprt — the transport context 🫶. that's the thing you're about to mess with.

---

✨ DESCRIPTION ✨

so here's the tea, bestie 🍓: if xprt is connected, this function disconnects it — not because anything's actually wrong, but to simulate spurious connection loss. it's fake-breaking things on purpose to see what happens. chaos as a service, fr fr 🔥

⚠️ okay but listen: the caller must hold xprt's send lock. no cap. that lock is what keeps the data structures and hardware resources stable while the rdma_disconnect call is happening. skip the lock and you're just out here living dangerously 💀 don't do that to yourself.
