finish_req(9)

💅 finish_req(9) — Kernel API Manual 🎀

okay so bestie, welcome to finish_req, straight out of the Kernel API Manual. this one is lowkey short but it's iconic, trust. ✨

---

🌸 NAME 🌸

finish_req — the little function that's used to invoke the complete callback from the requester when a request has been handled asynchronously. she's the "ok we're done here, go tell 'em" girlie 🫶

---

✨ SYNOPSIS ✨

void finish_req (struct iproc_reqctx_s *rctx , int err );

like, that's the whole signature. no notes. 💅

---

🦋 ARGUMENTS 🦋

• rctx — the request context. that's her. that's the main character. 👑
• err — tells you whether the request was successful or not. yes ma'am, this is the vibe check for success vs. not-success. 🔥

---

💖 DESCRIPTION 💖

Ensures that cleanup has been done for request. periodt. that's literally the whole job — making sure the cleanup already happened before we move on. 🌈

ngl this description is short but she said what she said — cleanup = handled. don't skip it. 💀
