ata_sas_queuecmd(9)

✨ ata_sas_queuecmd ✨

okay so bestie, welcome to the ata_sas_queuecmd page from the Kernel API Manual 💅 this one is short and sweet — like, it's literally a "hand off your SCSI command to libata" situation and honestly that's the whole vibe 🦋

---

🌸 NAME 🌸

ata_sas_queuecmd — issue SCSI cdb to libata-managed device 👑

like, you have a SCSI command descriptor block, the device is managed by libata, and this is the function that ships it over. no cap 💖

---

🎀 SYNOPSIS 🎀

int ata_sas_queuecmd (struct scsi_cmnd *cmd , struct ata_port *ap );

that's it, that's the whole signature, and yes she returns an int 💅

---

🫶 ARGUMENTS 🫶

• cmd — the SCSI command to be sent 📨 like, the actual cdb you're trying to get out the door.
• ap — the ATA port to which the command is being sent 🔥 this is the destination port, bestie.

---

⭐ RETURN ⭐

She gives you back the return value from __ata_scsi_queuecmd if cmd can be queued — and if it can't? you get 0 🫠 that's the whole deal, no secret lore here.

ngl the distinction is the entire personality of this function: queued → that inner return value, otherwise → 0. don't mix them up 😭
