ata_scsiop_maint_in(9)

🌸 ata_scsiop_maint_in(9) 🌸

okay so real quick before we dive in — this is a page straight outta the Kernel API Manual, and yes it's a (9) section page, meaning it's a kernel-internals moment, so grab your emotional support iced coffee 🍓 and let's go.

---

✨ NAME ✨

ata_scsiop_maint_in — literally simulates a subset of MAINTENANCE_IN. that's it, that's the whole vibe. a little taste of it. not the whole thing. a subset. 💅

---

🦋 SYNOPSIS 🦋

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

she takes three things and hands you back an unsigned int, no cap.

---

🎀 ARGUMENTS 🎀

• dev — the target device 💖 like, the ATA device we're talking about here.
• cmd — the SCSI command of interest 👀 the one we care about rn.
• rbuf — the response buffer, bestie. this is where the simulated SCSI cmd output gets sent 🫶 so all the pretend output goes in here.

---

🔥 DESCRIPTION 🔥

okay so what she actually does: yields a subset to satisfy scsi_report_opcode ✨ that's the whole job. she's not doing the full MAINTENANCE_IN experience, she's giving you just enough of a subset to keep scsi_report_opcode happy. king behavior honestly 👑

LOCKING: spin_lock_irqsave(host lock) 🔒 — yes she holds the host lock, and yes she does it with spin_lock_irqsave, so pls respect the lock, i'm begging 🙈
