hwi_write_buffer(9)

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

Okay so real talk, this one's from the hwi_write_buffer(9) page in the Kernel API Manual, and it's short and sweet but we're gonna make it iconic. ✨

---

🌸 NAME 🌸

hwi_write_buffer — literally just populates the WRB with task info. That's it. That's the whole vibe. 🫶

---

🦋 SYNOPSIS 🦋

int hwi_write_buffer (struct iscsi_wrb *pwrb , struct iscsi_task *task
);

So it hands you back an int, and it takes these two besties right here 👇

---

🎀 ARGUMENTS 🎀

• pwrb — ptr to the WRB entry. Yes bestie, this one's a pointer. It's the WRB entry and you're pointing right at it, no cap. 💅
• task — the iscsi task which is to be executed. This is the main character right here, the thing that's actually gonna get executed. 👑

🌈 SEE ALSO 🌈

The kernel file in question lives at ./drivers/scsi/be2iscsi/be_main.c, and here's the whole friend group you should go say hi to — no gatekeeping, all of them linked for you:

• be_isr_mcc(9)
• be_isr_msix(9)
• be_isr(9)
• alloc_wrb_handle(9)

• beiscsi_cleanup_task(9)
• beiscsi_alloc_pdu(9)
• beiscsi_bsg_request(9)

💀 Fair warning: this page is short. It tells you the function name, its signature, its two arguments, and its neighbours in the driver, and that is the entire delulu. No return-value essay, no "errors" section. So don't go making stuff up, iykyk. 🙈

That's the whole page, bestie — go populate that WRB. 🍓 Sourced from ./drivers/scsi/be2iscsi, dated October 2026, and honestly? Slay. 🧚‍♀️💜
