ata_dev_revalidate(9)

💖 NAME 💖

ata_dev_revalidate — Revalidate ATA device. okay so bestie, this is the ata_dev_revalidate(9) page from the Kernel API Manual 💅 and it's literally about giving an ATA device a lil revalidate check. iconic behavior only.

🌸 SYNOPSIS 🌸

int ata_dev_revalidate (struct ata_device *dev , unsigned int new_class
       , unsigned int readid_flags );

🎀 ARGUMENTS 🎀

• dev — the device to revalidate, bestie.
• new_class — the new class code.
• readid_flags — the read ID flags.

💖 DESCRIPTION 💖

okay so what happens is: re-read the IDENTIFY page, make sure dev is still attached to the port, and reconfigure it according to the new IDENTIFY page. that's the whole glow-up ✨

🔒 LOCKING: Kernel thread context (may sleep). so yes, it can absolutely nap, and you need to be in kernel thread context. no cap.

🦋 RETURN 🦋

0 on success, negative errno otherwise. slay. 💅
