ata_sff_thaw(9)

💅 ata_sff_thaw(9)

okay so this is a page straight out of the Kernel API Manual (yes that Kernel API Manual, the one your compsci prof keeps mentioning like it's a celebrity) and honestly? it's a short one. a little baby page. but we're gonna give it the full main character treatment anyway 🎀

---

✨ NAME ✨

ata_sff_thaw — the function that thaws an SFF controller port. that's it. that's the whole vibe. 🧊➡️🌊

---

🦋 SYNOPSIS 🦋

void ata_sff_thaw (struct ata_port *ap );

no like literally that's it. void return, one arg, we move. 💅

---

🌸 ARGUMENTS 🌸

• ap — the port you're thawing out. this is the one (1) thing you hand it. give it the port, bestie, that's the whole job 🫶

---

⭐ DESCRIPTION ⭐

so what does it do. it thaws the SFF controller port. yep. the description on this one is doing the absolute bare minimum and honestly? respect. it said what it said and it left. 🔥

LOCKING: inherited from the caller. read that again, bestie — it does not handle its own locking, it just inherits whatever you set up. so if your locking is a mess, that's a you problem, not an ata_sff_thaw problem 🙈 no cap.
