rvt_put_qp(9)

💅 rvt_put_qp(9) — from the Kernel API Manual, bestie 🎀

Okay so picture this: we're deep in the kernel, include/rdma territory, and it's time to let a QP go. This little function is the "you can leave now, queen" moment. ✨

---

✨ NAME ✨

rvt_put_qp — release a QP reference. That's it, that's the whole vibe. Dropping a ref like it's a toxic group chat. 💅

---

🌸 SYNOPSIS 🌸

void rvt_put_qp (struct rvt_qp *qp );

Literally returns nothing (void, icon behaviour) and takes exactly one thing. No cap. 🦋

---

🎀 ARGUMENTS 🎀

• qp — the QP to release. Hand it over, bestie, we're letting it go. 🫶

Okay that's the whole page, babe — sourced straight from ./include/rdma, dated October 2026, and yes, that date is giving future main character energy. Go forth and release your QPs responsibly. 🌈💜
