ata_scsiop_mode_sense(9)

💖 ata_scsiop_mode_sense(9) 💖

okay bestie, so this one lives in the Kernel API Manual and it's literally the fake-out queen of the SCSI world 👑 — it's about pretending. Let's get into it ✨

---

🌸 NAME 🌸

ata_scsiop_mode_sense — Simulate MODE SENSE 6, 10 commands 🎀

---

🦋 SYNOPSIS 🦋

unsigned int ata_scsiop_mode_sense (struct ata_device *dev , struct
       scsi_cmnd *cmd , u8 *rbuf );

---

💜 ARGUMENTS 💜

• dev — the target device, the main character of this whole situation 🫶
• cmd — the SCSI command we're interested in, iykyk 👀
• rbuf — the response buffer, aka where the simulated SCSI cmd output gets sent 📬

---

🌈 DESCRIPTION 🌈

So it simulates MODE SENSE commands. That's the whole vibe. 💅

Lowkey important assumption bestie: assume this is invoked for direct access devices only — like disks, fr fr. For any other device type there should be no block descriptor. Not a single one. Not even a little one. 🚫

LOCKING: spin_lock_irqsave(host lock) — no cap, that's the lock, respect it 😭✨

k that's the whole page bestie, you ate that 💅✨

shoutout to ./drivers/ata for being the source, and to October 2026 for the date — iconic era, we were all there 🎀🦋 go forth and simulate, mwah 💖
