ata_dev_next(9)

💅 ata_dev_next — the device iteration helper, bestie

okay so this one is from the Kernel API Manual, and it's called ata_dev_next(9). she's a device iteration helper and honestly she's giving "walk the list, find your next friend" energy 🫶

---

✨ SYNOPSIS ✨

struct ata_device * ata_dev_next (struct ata_device *dev , struct
ata_link *link , enum ata_dev_iter_mode mode );

like... look at her go 💅 three args, one pointer back, no drama.

---

🎀 ARGUMENTS 🎀

• dev — the previous device, bestie. if you're just starting out and have no ex yet, pass NULL and she'll take it from the top 💖
• link — the ATA link that's holding all the devices you wanna walk through. she lives here, that's her whole world 🦋
• mode — the iteration mode, and it's one of the ATA_DITER_* girls. pick your vibe ✨

---

🌸 DESCRIPTION 🌸

LOCKING: Host lock or EH context. no cap, that's the rule — hold the host lock or already be chillin' in EH context. don't come at her any other way 😭

---

⭐ RETURN ⭐

Pointer to the next device. that's it, that's the whole gift 🎁

mwah 💜 that's the whole page, and it dropped in ./drivers/ata back in October 2026 — so go forth, iterate those devices, and slay ✨💅
