💅 ata_is_ata_dev(9) — a Kernel API Manual moment

ok so bestie, this is a page from the Kernel API Manual and it's about one tiny little function, ata_is_ata_dev, and honestly? it's giving humble icon. it does one (1) thing and it does it slayfully. let's get into it 🎀

✨ NAME ✨

ata_is_ata_dev — check if a struct device represents a ATA device

like literally that's the whole gig. it looks at a device and is like "hm. ATA or not ATA." a vibe check, but for hardware 💅

✨ SYNOPSIS ✨

bool ata_is_ata_dev (const struct device *dev );

(yes the spacing is exactly like that, don't come for me, that's how it's written 🫶)

✨ ARGUMENTS ✨

  • dev — the device to check. that's it. that's the whole argument list. hand it a device and it'll tell you what's up ✨

✨ RETURN ✨

  • true → the device represents a ATA device 👑
  • false → it does not. heartbreaking, but accurate 😭

no cap, that's the entire return contract. boolean, binary, no in-between, main character energy fr fr.

✨ SEE ALSO ✨

ok so if you're doing a deep dive (and honestly, obsessed that you are), the kernel file to look at is:

./drivers/ata/libata-transport.c

and these are the lil sibling functions in the family group chat 🌸:

go read them, they're all lowkey doing their own iconic thing 🦋

ngl bestie, this one's short and sweet — no scary caveats, no warnings, no undefined behaviour lurking in the shadows. just a bool and a dream 💖

and that's the page!! 🧚 this cutie lives over in ./drivers/ata, and the version we're reading is the October 2026 one — so if you're citing it, that's the date to drop ⭐ mwah, go check your devices, ily, bye 💜
