ata_scsi_qc_new(9)

💅 ata_scsi_qc_new(9) — like, the Kernel API Manual page you actually wanna read 🎀

okay so bestie, welcome to the ata_scsi_qc_new glow-up page — straight out of the Kernel API Manual and honestly? it's giving "small function, big main character energy." ✨

---

🌸 NAME 🌸

ata_scsi_qc_new — acquire new ata_queued_cmd reference

(yes literally, that's the whole name section, she's concise, she's iconic, she doesn't need more 💅)

---

🦋 SYNOPSIS 🦋

struct ata_queued_cmd * ata_scsi_qc_new (struct ata_device *dev , struct scsi_cmnd *cmd );

---

✨ ARGUMENTS ✨

• dev — the ATA device that this brand-new command is getting attached to 🫶
• cmd — the SCSI command that originated this whole ATA command situation. she's the reason we're all here fr fr.

---

🔥 DESCRIPTION 🔥

So what does she do? She obtains a reference to an unused ata_queued_cmd structure — which, no cap, is the basic libata structure representing a single ATA command sent to the hardware. like, the fundamental unit of "hey hardware, do the thing." 👑

And if a command was available? Then she fills in the SCSI-specific portions of that structure with all the info about the current command. slay. 💖

LOCKING: spin_lock_irqsave(host lock) — that's the lock she's operating under, bestie. noted, memorized, tattooed. 🧚

---

⭐ RETURN ⭐

• Command allocated ✅
• or NULL if none available 😭

that's it. that's the return. binary queen.
