hw_failure_e..._action_func(9)

💖 hw_failure_emergency_action_func(9) 💖

okay bestie, welcome to the Kernel API Manual page for hw_failure_emergency_action_func(9) — this is the emergency-action work situation, and it is lowkey iconic in a “do not panic but also the kernel might need to force a poweroff or reboot” way. 🚨💅

🌸 NAME 🌸

hw_failure_emergency_action_func — emergency action work after a known delay. That’s the vibe: emergency action work, known delay, no surprises. ✨

✨ SYNOPSIS ✨

Here’s the signature exactly, character-for-character, because we do not freestyle code:

void hw_failure_emergency_action_func (struct work_struct *work );

🎀 ARGUMENTS 🎀

• work — the work_struct associated with the emergency action function. This is the one argument, bestie; it’s literally the work struct tied to the emergency action function. 🛠️

🚨 DESCRIPTION 🚨

okay so this function gets called in very critical situations — the kind where it needs to force a kernel poweroff or reboot after a configurable timeout value. That’s the whole emergency-action-work-after-a-known-delay vibe: critical situation, forced poweroff or reboot, configurable timeout. It’s giving last-resort main character energy, and ngl it is not a drill. 💅🔥
