svc_rqst_release_pages(9)

💅 svc_rqst_release_pages — like, the Kernel API Manual page for it, bestie ✨

okay so real talk, this is a page from the Kernel API Manual (section 9, iykyk) and it's all about svc_rqst_release_pages. yes that's a mouthful. no we're not renaming it. let's go 🫶

---

✨ NAME ✨

svc_rqst_release_pages — Release Reply buffer pages 💖

---

🌸 SYNOPSIS 🌸

void svc_rqst_release_pages (struct svc_rqst *rqstp );

that's it. that's the whole signature. iconic, honestly. ✨

---

🎀 ARGUMENTS 🎀

• rqstp — the RPC transaction context. that's your little ✨situation✨, the context for the RPC transaction you're working with.

---

🦋 DESCRIPTION 🦋

okay so bestie, here's the tea ☕ — this function releases the response pages that live in the range [rq_respages, rq_next_page). lowkey it's just cleanup duty but it ate.

and here's the cute part: NULL entries in that range get skipped entirely 🙈 — which is on purpose, fr fr. it lets transports yeet pages over to a send context before this function even runs. so like, not every slot needs to be a real page and that's fine, we just skip the empty ones. 💅

no cap, if you're expecting every entry to be a live page, vibe check yourself first — the NULLs are a feature, not a bug. 🧚
