💖 lpfc_els_hbq_alloc(9) — the kernel API manual, bestie edition 💖

Okay so you're out here in <cyan>lpfc_els_hbq_alloc(9)</cyan> territory, the kernel API manual zone, and honestly? This one's a little cutie. Let's get into it. 🎀

✨ NAME ✨

lpfc_els_hbq_alloc — Allocate an HBQ buffer 🦋

---

🌸 SYNOPSIS 🌸

struct hbq_dmabuf * lpfc_els_hbq_alloc (struct lpfc_hba *phba );

---

💜 ARGUMENTS 💜

• phba — the HBA you're allocating that HBQ buffer for, periodt.

---

🧚 DESCRIPTION 🧚

So what it does is: it allocates a DMA-mapped HBQ buffer out of the lpfc_hrb_pool PCI pool, okay? And along with it, you also get a non-DMA-mapped container for that buffer. Two-for-one situation, we love to see it. ✨

---

🔥 NOTES 🔥

Not interrupt-safe. 🚨 Must be called with no locks held. Like, zero locks. None. Don't try it.

---

👑 RETURN 👑

Pointer to HBQ on success, NULL on failure. That's the whole vibe check. 💅
