🌸 mv_fill_sg(9) — like, the whole vibe 🌸

okay so bestie, we're in the mv_fill_sg(9) era of the Kernel API Manual and honestly? it's giving "small function, big job." let's get into it 💅

✨ NAME ✨

mv_fill_sg — fills out the Marvell ePRD (that's scatter gather, iykyk) entries 🎀

---

🦋 SYNOPSIS 🦋

void mv_fill_sg (struct ata_queued_cmd *qc );

literally that's it. that's the whole signature. no cap. ✨

---

💖 ARGUMENTS 💖

• qc — the queued command whose SG list we're sourcing from. it's the main character here, we're just reading off its SG list, periodt. 👑

---

🌈 DESCRIPTION 🌈

so what does this thing actually do? it populates the SG list and then marks the last entry. that's the whole assignment, and it ate. 🔥

LOCKING: inherited from the caller — not us, not our problem, we're just the vibes inheriting the lock situation from whoever called us. fr fr. 🔒
