💅 xprt_release_xprt_cong — Kernel API Manual, section 9

okay so you're reading the xprt_release_xprt_cong(9) page, bestie. it lives in section 9 of the Kernel API Manual and it's genuinely so cozy once you get it. let's go 🫶

---

🌸 NAME 🌸

xprt_release_xprt_cong — allow other requests to use a transport

---

✨ SYNOPSIS ✨

void xprt_release_xprt_cong (struct rpc_xprt *xprt , struct rpc_task
*task );

---

🎀 ARGUMENTS 🎀

• xprt — the transport, aka the one where other tasks might be lowkey waiting their turn 👀
• task — the task that's releasing access to the transport, main character behavior fr

---

🦋 DESCRIPTION 🦋

so here's the vibe check: note that task can be NULL. not me pointing that out but yes, NULL is valid, don't panic 💀

another task gets awoken to use the transport if the transport's congestion window allows it. that's the whole point — you release, someone else gets woken up, everybody eats 🔥
