ata_eh_set_pending(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ata_eh_set_pending(9) — like, the kernel API manual, but make it make sense 🎀

okay so bestie, welcome to the Kernel API Manual, section 9 (kernel functions, iykyk). Today's main character is ata_eh_set_pending, and honestly? she's a tiny little function with one job and she does it flawlessly. Let's get into it ✨

✨ NAME ✨

ata_eh_set_pending — sets ATA_PFLAG_EH_PENDING and activates fast drain 💅

🦋 SYNOPSIS 🦋

void ata_eh_set_pending (struct ata_port *ap , bool fastdrain );

🌸 ARGUMENTS 🌸

  • ap — the target ATA port 👑 the one we're flagging, the main character of this whole operation
  • fastdrain — activate fast drain ⚡ yes/no vibes, it's a bool

💖 DESCRIPTION 💖

So here's the tea 🍓: this function sets ATA_PFLAG_EH_PENDING and activates fast drain if fastdrain is non-zero and EH wasn't already pending before. Like, no double-flagging, that's not the vibe 🙈

And what does fast drain even do? It ensures that EH kicks in in a timely manner ⏰ periodt. That's it, that's the whole personality.
