💖 pc87413_notify_sys(9) 💖

okay bestie, welcome to the Kernel API Manual page for pc87413_notify_sys(9). It's giving shutdown-notifier realness, and we're gonna keep every tiny detail intact. periodt. ✨

🌸 NAME 🌸

pc87413_notify_sys — that's the whole name entry, bestie; the source doesn't add a description after the dash. 💅

✨ SYNOPSIS ✨

int pc87413_notify_sys (struct notifier_block *this , unsigned long code , void *unused );

🦋 ARGUMENTS 🦋

• this — our notifier block. 👑
• code — the event being reported. 🔥
• unused — unused. 💀

🎀 DESCRIPTION 🎀

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