svc_max_payload(9)

💅 svc_max_payload — it's giving payload limit realness

okay so bestie, this one's from section 9 of the Kernel API Manual, and it's honestly such a little icon — short, sweet, and it answers exactly one question. Let's get into it 🫶

---

✨ NAME ✨

svc_max_payload — the way this function tells you the transport-specific limit on the RPC payload 🎀

---

🌸 SYNOPSIS 🌸

u32 svc_max_payload (const struct svc_rqst *rqstp );

that's it. that's the whole vibe check. one arg in, a u32 out 💖

---

🦋 ARGUMENTS 🦋

• rqstp — your RPC transaction context, aka the main character of this whole operation 👑

---

⭐ DESCRIPTION ⭐

So here's the tea: it returns the maximum number of payload bytes that the current transport allows. lowkey important, highkey simple. no cap, that's literally the whole function 💀✨
