ata_link_online(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual — this one's a lil function page and it's genuinely so cute and short, you're gonna eat it up. It's ata_link_online(9), aka the vibe-check function for ATA links ✨

✨ NAME ✨

ata_link_online — the way that this thing literally just tests whether the given link is online 🦋

🌸 SYNOPSIS 🌸

bool ata_link_online (struct ata_link *link );

🎀 ARGUMENTS 🎀

  • link — the ATA link you wanna test. that's it. that's the whole argument, she's low maintenance 💅

🧚 DESCRIPTION 🧚

Okay so the whole point: this tests whether link is online. that's the assignment, and she understood it 👑

Here's the tea though — when there's no slave link, this is identical to ata_phys_link_online. same energy, same result, no notes.

But when there is a slave link? Then bestie, listen: this function should only be called on the master link, and it will return true if any of the M/S links is online. like, she's checking the whole group chat, not just one person's read receipts 👀

LOCKING: None. zero. nada. no locks here. it's giving "no cap, no mutex" 🙈

⭐ RETURN ⭐

True if the port online status is available and online. both things, periodt. if it's not available, don't come crying to her 💀
