ata_host_detach(9)

💅 ata_host_detach(9) 💅

okay so this is the Kernel API Manual page for one very specific cleanup moment: detaching every port from an ATA host. It's giving “bye bestie, all ports are leaving the group chat” energy, and honestly? Iconic. 💖

🌸 NAME 🌸

ata_host_detach — detach all ports of an ATA host. That's the whole mission, and it ate. ✨

✨ SYNOPSIS ✨

Here's the signature, no cap:

void ata_host_detach (struct ata_host *host );

🎀 ARGUMENTS 🎀

• host — the host to detach. That's it, that's the argument, she's simple and effective. 🫶

🦋 DESCRIPTION 🦋

So what does it actually do? It detaches all ports of host. All of them. Full port detachment era. 💅

LOCKING: Kernel thread context (may sleep). That's the locking note, bestie — it may sleep, so keep that in mind. 😭
