svc_reserve(9)

💖 NAME 💖

okay so bestie, welcome to svc_reserve(9) from the Kernel API Manual 🫶 — it’s the function that changes the space reserved for the reply to a request. literally its whole job, no cap 💅

svc_reserve — change the space reserved for the reply to a request. periodt ✨

---

🎀 SYNOPSIS 🎀

void svc_reserve (struct svc_rqst *rqstp , int space );

---

🌸 ARGUMENTS 🌸

• rqstp — the request in question, aka the main-character request we’re looking at 👑
• space — the new max space to reserve, fr fr

---

🦋 DESCRIPTION 🦋

So here’s the vibe: each request reserves some space on the output queue of the transport to make sure the reply fits. cute, responsible, we love that for it 💖

This function reduces that reserved space to be the amount of space used already, plus space. that’s it, that’s the whole glow-up ✨
