wdtpci_notify_sys(9)

💅 wdtpci_notify_sys(9) — Kernel API Manual 💅

okay bestie, welcome to the kernel-side group chat: this is wdtpci_notify_sys(9), straight from the Kernel API Manual. No cap, it’s a whole notifier situation. 🫶

---

🎀 NAME 🎀

wdtpci_notify_sys — and that’s literally it, bestie; the original gives no extra blurb here. Periodt. 💅

---

✨ SYNOPSIS ✨

Here’s the exact signature, character-for-character, because we do not mess with code:

int wdtpci_notify_sys (struct notifier_block *this , unsigned long code
       , void *unused );

---

🌸 ARGUMENTS 🌸

• this — our notifier block, hi bestie 👋
• code — the event being reported, iykyk
• unused — unused. Just sitting there, iconic but not doing much 🧚

---

🔥 DESCRIPTION 🔥

okay so our notifier gets called on system shutdowns. We want to turn the card off at reboot — otherwise the machine will reboot again during memory test or, worse yet, during the following fsck. This would suck. In fact, trust me: if it happens, it does suck. 😭💀

no cap, that’s the whole plot: shutdown-time notifier energy, card-off-at-reboot agenda, and a deeply real fear of a second reboot ruining everyone’s day. 🫠
