💅 rvt_dereg_clean_qps(9)

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function page, rvt_dereg_clean_qps — and yes it's as niche as it sounds, but we're gonna slay it together 🫶

---

✨ NAME ✨

rvt_dereg_clean_qps — find QPs for reference cleanup 🔍

like, the whole vibe is: go hunt down the QPs so the references can get cleaned up. periodt.

---

🎀 SYNOPSIS 🎀

void rvt_dereg_clean_qps (struct rvt_mregion *mr );

that's it, that's the whole signature 💀 returns void, takes one thing. no cap.

---

🌸 ARGUMENTS 🌸

• mr — the MR that's being deregistered. that's the memory region we're saying bye to 👋💔

---

💖 DESCRIPTION 💖

so what does it actually do? bestie. this routine iterates RC QPs looking for references to the lkey noted in mr 🔥

that's the whole bit — it walks the RC QPs, checks 'em for refs to the lkey that lives in mr, and that's how it finds the QPs that need reference cleanup. it's giving main character energy for the cleanup process ngl 💅

no weird edge cases here, no return value to check — it's void, so literally nothing comes back at you 😌
