svc_rdma_encode_read_list(9)

✨ svc_rdma_encode_read_list ✨

okay so bestie, welcome to the Kernel API Manual page for svc_rdma_encode_read_list 💅 yes that's a whole mouthful and yes it's iconic, we move.

---

🎀 NAME 🎀

svc_rdma_encode_read_list — it encodes the RPC Reply's Read chunk list. that's the whole vibe. no cap.

---

🦋 SYNOPSIS 🦋

ssize_t svc_rdma_encode_read_list (struct svc_rdma_send_ctxt *sctxt );

like, one function, one argument, one return type. clean. minimal. main character energy honestly 💖

---

🌸 ARGUMENTS 🌸

• sctxt — this is the send context for the RPC Reply, aka the little container that's holding all your reply-sending business together. give it a kiss, it's doing the work 🫶

---

🔥 DESCRIPTION 🔥

so here's the tea on what it gives back ☕✨ — the return values, fr fr:

• on success? it returns the length in bytes of the Reply XDR buffer that was consumed by the Reply Read list. slay, it tells you exactly how much it ate 💅
• and if the XDR buffer overflows? you get -EMSGSIZE. not the moment, but that's what it does 😭

that's literally it, and honestly the way that it just does its one job is so refreshing ngl 👑
