💅 scsi_unlock_floptical(9) — a Kernel API Manual moment

okay so bestie, welcome to scsi_unlock_floptical(9), a page from the Kernel API Manual, and honestly? it's a tiny little icon and we're gonna get through it together 🫶

---

✨ NAME ✨

scsi_unlock_floptical — unlock the device via a special MODE SENSE command 🔓✨

like yes, that's the whole vibe. unlocking. via MODE SENSE. special edition.

---

🌸 SYNOPSIS 🌸

void scsi_unlock_floptical (struct scsi_device *sdev , unsigned char
*result );

no cap, that's literally the signature. void return, two args, we move.

---

🎀 ARGUMENTS 🎀

• sdev — the scsi device you're sending the command to 💌 like, this is the target of the whole operation bestie
• result — the area where the result of the MODE SENSE gets stored 📥 that's where the tea lands

---

🦋 DESCRIPTION 🦋

so here's what's actually happening: it sends a vendor specific MODE SENSE command — and listen, that's MODE SENSE, not MODE SELECT, do not get it twisted, I will not be repeating myself 🙈 — and it gets called for BLIST_KEY devices. that's it. that's the function. short queen energy 👑

fr fr though: it's a vendor specific MODE SENSE, not a MODE SELECT, and it's for BLIST_KEY devices. that's the whole lore.
