ipr_timeout(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

Bestie, meet ipr_timeout — she's the one who shows up when an internally generated op has timed out. Periodt. This little page lives in the Kernel API Manual, manual section 9, and yes she's that girl. 💅

✨ SYNOPSIS ✨

void ipr_timeout (struct timer_list *t );

(Yes the space before the ) is real, don't @ me, copy it exactly. 🫶)

🫶 ARGUMENTS 🫶

  • t — the timer context, and it's the plug for the whole thing: it's how we fetch the ipr command struct. Think of it as the group chat where the command's receipts are stored. 💖

🔥 DESCRIPTION 🔥

Okay so here's the tea. ☕ When this fires, she blocks host requests and initiates an adapter reset. That's it, that's the whole job — no cap.

It's giving "everything pause, we're resetting the adapter," and honestly? Iconic. She doesn't ask questions, she doesn't negotiate, she just blocks those host requests and kicks off the adapter reset. Main character energy only. 👑

Return value: none — she gives you nothing back and she doesn't need to. 💀

👑 SEE ALSO 👑

Right, this is the part where you meet her entire friend group — the kernel file she lives in is ./drivers/scsi/ipr.c, and every single one of these queens is linked up:
