lpfc_els_free_bpl(9)

💅 lpfc_els_free_bpl — Kernel API Manual

okay bestie, so this one's from the lpfc_els_free_bpl(9) manual, which is a kernel API page for the lpfc driver — yes we're in kernel land, yes it's giving big-brain energy, and yes i'm gonna walk you through it ✨

---

✨ NAME ✨

lpfc_els_free_bpl — literally: free lpfc dma buffer and data structure with bpl 🎀

---

🦋 SYNOPSIS 🦋

int lpfc_els_free_bpl (struct lpfc_hba *phba , struct lpfc_dmabuf
*buf_ptr );

that's the whole signature, no cap. two args, returns an int 💖

---

🌸 ARGUMENTS 🌸

• phba — pointer to lpfc hba data structure. like, the hba itself, bestie 👑
• buf_ptr — pointer to the lpfc dma buffer data structure. the thing we're about to set free 🕊️

---

💜 DESCRIPTION 💜

so what does this icon actually do? this routine releases the lpfc Direct Memory Access (DMA) buffer associated with a Buffer Pointer List (BPL) back to the lpfc DMA buffer pool. lowkey it's just returning the buffer to the pool so it can be reused — main character behavior of memory management fr fr 💅

Return code 0 — Successfully released lpfc DMA buffer (currently, always return 0) 🫶

ngl, that "currently, always return 0" is doing a lot of heavy lifting. like yes it's 0 today but the API still has a return code, so don't go assuming it's decorative. iykyk 😭

okay that's the whole page, bestie. it's short and it ate 💅 one buffer freed, one pool restored, zero drama.

and before i go — tiny sign-off moment 🎀 this page lives in ./drivers/scsi/lpfc, dated October 2026, and it's still filed under lpfc_els_free_bpl(9) in case you need to find it later. periodt 💖✨🦋
