xprt_wait_f..._request_rtt(9)

✨ NAME ✨

okay so this is the xprt_wait_f..._request_rtt(9) page from the Kernel API Manual, bestie 💅 and the whole vibe is:

xprt_wait_for_reply_request_rtt — wait for a reply using the RTT estimator 🎀

---

🌸 SYNOPSIS 🌸

void xprt_wait_for_reply_request_rtt (struct rpc_task *task );

like, that's the whole signature. no cap. 🫶

---

🦋 ARGUMENTS 🦋

• task — a pointer to an rpc_task, literally just the task you're dealing with 💜

---

💖 DESCRIPTION 💖

So what this one does is: it sets a request's retransmit timeout using the RTT estimator, and then puts the task to sleep on the pending queue. 😴✨ That's it, that's the whole personality. the way it just… handles the timeout and tucks the task in? iconic. 👑
