rvt_qp_iter_next(9)

💖 NAME 💖

rvt_qp_iter_next — return the next QP in iter. Okay bestie, this is the rvt_qp_iter_next(9) page from the Kernel API Manual, and it's literally the little iterator step that hands you the next QP. 🍓

---

🦋 SYNOPSIS 🦋

int rvt_qp_iter_next (struct rvt_qp_iter *iter );

---

🎀 ARGUMENTS 🎀

• iter — the iterator. That's the whole argument, no cap. 🫶

---

🌸 DESCRIPTION 🌸

This is a fine grained QP iterator that's suitable for use with debugfs seq_file mechanisms. It's giving very focused, very debug-friendly energy. ✨

When the return value is 0, it updates iter->qp with the current QP. So yeah, that's the main-character move right there. 💅

---

⭐ RETURN ⭐

Vibe check on the return values:

• 0 — iter->qp is valid. Slay, you got one. 💖
• 1 — no more QPs. That's the end, bestie. 😭

Mwah 💋 — cute little sign-off from the footer: source path ./drivers/infiniband/sw/rdmavt, date October 2026, and the page signs itself rvt_qp_iter_next(9). 🫶
