💅 ata_bmdma_dumb_qc_prep — Kernel API Manual 🎀

okay so bestie, welcome to the <pink>Kernel API Manual</pink> page for ata_bmdma_dumb_qc_prep, and honestly? she's a little legend. small function, big job. let's get into it ✨

---

✨ NAME ✨

ata_bmdma_dumb_qc_prep — Prepare taskfile for submission 🫶

---

🌸 SYNOPSIS 🌸

enum ata_completion_errors ata_bmdma_dumb_qc_prep (struct ata_queued_cmd
*qc );

like, that's the whole vibe. one pointer in, one enum ata_completion_errors out. slay.

---

🦋 ARGUMENTS 🦋

• qc — Metadata associated with taskfile to be prepared. that's it, that's the whole argument. she's the little info packet for the taskfile we're about to prep 💖

---

🌈 DESCRIPTION 🌈

Prepare ATA taskfile for submission. literally what it says on the tin. takes the metadata in qc, gets the taskfile all dressed and ready to be handed off. no cap, that's the entire description — she's concise and she knows it 💅

🔒 LOCKING 🔒

spin_lock_irqsave(host lock)

fr fr, that's the locking context — the host lock gets taken with spin_lock_irqsave. not me reminding you to respect the lock 🙈
