ata_scsiop_inq_80(9)

💖 ata_scsiop_inq_80(9) — a whole vibe from the Kernel API Manual 🎀

okay bestie, sit down, hydrate, and let me tell you about ata_scsiop_inq_80(9), which is genuinely one of the cutest little functions in the whole kernel API, no cap. it lives in the Kernel API Manual and it's basically the wingman that fakes a SCSI answer for you. 💅

---

✨ NAME ✨

ata_scsiop_inq_80 — okay so what it does is simulate INQUIRY VPD page 80, device serial number. that's it, that's the whole job, and it does it flawlessly fr fr 🦋

---

🌸 SYNOPSIS 🌸

unsigned int ata_scsiop_inq_80 (struct ata_device *dev , struct
scsi_cmnd *cmd , u8 *rbuf );

look at her. three arguments, one unsigned int coming back at you. iconic behavior honestly 👑

---

🎀 ARGUMENTS 🎀

• dev — your target device, the main character of this whole operation. who we doing this for? her. 💖
• cmd — the SCSI command of interest, i.e. the one we're currently obsessed with. 🔥
• rbuf — the response buffer, and this is where the simulated SCSI cmd output gets sent. it's the group chat that receives the message, basically. 📨

---

🦋 DESCRIPTION 🦋

Returns ATA device serial number. that's the whole plot. she hands you the serial number and she does not make a thing of it. lowkey humble of her. 🥹

LOCKING: spin_lock_irqsave(host lock)

⚠️ bestie, note the locking situation before you go touching anything: it's spin_lock_irqsave(host lock). that's not a suggestion, that's the rule. 💀
