qla_chk_cont_iocb_avail(9)

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

Okay so picture this: you're deep in the kernel, section 9, and you need to know if all the continuation iocbs have shown up before you're even allowed to start processing iocbs. That's literally the whole job of qla_chk_cont_iocb_avail — it checks whether every single continuation iocb is available before iocb processing can start. No cap. 🎀

---

✨ SYNOPSIS ✨

int qla_chk_cont_iocb_avail (struct scsi_qla_host *vha , struct rsp_que
*rsp , response_t *pkt , u32 rsp_q_in );

Four arguments, one int coming back at you. Let's get into who's who 🫶

---

🌸 ARGUMENTS 🌸

• vha — the host adapter pointer. Your main character struct, honestly.
• rsp — the respond queue. (Yes, the manpage says "respond queue" — we're keeping it exactly like that, periodt.)
• pkt — the head iocb, the one that describes how many continuation iocb there are. It's giving "leader of the pack" energy 👑
• rsp_q_in — -- undescribed -- 🙈 like the docs literally did not describe this one. We're not gonna invent lore for it either, bestie. It exists. That's what we know.

---

⭐ RETURN ⭐

• 0 — all iocbs has arrived 🎉 (yes, "has" — we're quoting the vibes exactly)
• xx — all iocbs have not arrived 😭 not yet, come back later
