okay so welcome to the Kernel API Manual, bestie, and today's main character is lpfc_in_buf_free(9) — the little cleanup function that could 🫶

🎀 NAME 🎀

lpfc_in_buf_free — Free a DMA buffer 💖

---

✨ SYNOPSIS ✨

void lpfc_in_buf_free (struct lpfc_hba *phba , struct lpfc_dmabuf *mp );

literally that's the whole signature, no cap 🔥

---

🦋 ARGUMENTS 🦋

• phba — the HBA that this buffer is associated with 👑
• mp — the buffer we're about to free 🎀

---

🌸 DESCRIPTION 🌸

so basically this frees the given DMA buffer in the appropriate way, and "appropriate" is doing a LOT of work in that sentence 👀 — it depends on if the HBA is running in SLI3 mode with HBQs enabled. that's the vibe check it does before it commits, okurrr 💅

---

💜 NOTES 💜

• it takes phba->hbalock 🔒
• it can be called with or without other locks held — so flexible, so iconic ⭐

---

🌈 RETURN 🌈

None 🙈 — it returns nothing, it just does the thing and dips 💀
