pc87413_release(9)

💖 NAME 💖

okay so this is pc87413_release(9) from the Kernel API Manual, and bestie, the short description after the dash is literally blank in the original page — no invented summary here, we respect the mystery 💅✨

🎀 SYNOPSIS 🎀

int pc87413_release (struct inode *inode , struct file *file );

🦋 ARGUMENTS 🦋

• inode — the inode that’s headed to the board 🫶
• file — the file handle for the board 💖

🌸 DESCRIPTION 🌸

okay so the watchdog has a configurable API, and this is where the drama lives 😭 there is a whole religious dispute between two camps:

• the people who want their watchdog to be able to shut down 🛑
• the people who want to be sure that if the watchdog manager dies, the machine reboots 🔁

in the former case, we disable the counters. in the latter case, you have to open it again very soon. that’s the whole vibe check, fr fr 💅
