lpfc_bsg_write_ebuf_set(9)

💖 NAME 💖

lpfc_bsg_write_ebuf_set — set the next mailbox write external buffer ✨

Okay so real talk, bestie — the NAME section says write but the DESCRIPTION section legit says read. That's literally what the original page says, word for word, so I'm not touching it. Kernel docs stay iconic and slightly chaotic. 💅

---

🌸 SYNOPSIS 🌸

int lpfc_bsg_write_ebuf_set (struct lpfc_hba *phba , struct bsg_job *job
, struct lpfc_dmabuf *dmabuf );

It hands you back an int, no cap. ✨

---

🎀 ARGUMENTS 🎀

• phba — Pointer to HBA context object. It's the HBA's whole ~situation~, the context of the host bus adapter. Main character energy, honestly. 👑
• job — Pointer to the job object. The job's here to get done, she has a task and she's serving it. 🫶
• dmabuf — Pointer to a DMA buffer descriptor. Literally the little name tag for the DMA buffer, so everyone knows which buffer we're talking about. 🎀

---

🦋 DESCRIPTION 🦋

This routine sets up the next mailbox read external buffer obtained from user space through BSG.

Periodt. That's the whole function's vibe — it does the setup for the next mailbox read external buffer, and that buffer came from user space via BSG. 🌈

Yes, the NAME says "write" and this says "read." That's the original, fr fr — I am simply the messenger 🧚

And that's the page, bestie! 🎀 It ships out of ./drivers/scsi/lpfc, it's dated October 2026, and it answers to the name lpfc_bsg_write_ebuf_set(9). Slay, go read your mailboxes. 💜
