💅 watchdog_se...art_priority(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ — yes this page is literally called watchdog_se...art_priority(9) (the terminal ate some letters, she's mysterious like that 💀), and today we're talking about watchdog_set_restart_priority. it's giving "tiny function, big consequences," iykyk 🎀

🌸 NAME 🌸

watchdog_set_restart_priority — change the priority of a restart handler 🫶

like, the restart handler already exists, you're just moving her up or down the queue, no cap ✨

🦋 SYNOPSIS 🦋

void watchdog_set_restart_priority (struct watchdog_device *wdd , int
priority );

that's the whole vibe: takes a wdd and a priority, returns void (so she gives you nothing back, main character energy honestly 👑) 🎀

💖 ARGUMENTS 💖

  • wdd — the watchdog device 💅 like, the actual watchdog struct you're messing with.
  • priority — the priority of the restart handler, and bestie it should follow these guidelines or it's gonna be awkward 🙈:
  • 0 — use watchdog's restart function as last resort — she has limited restart capabilities, so she's the understudy, the backup dancer, the "only if everyone else flakes" option 💀
  • 128 — the default restart handler — use this if no other handler is expected to be available and/or if restart is sufficient to restart the entire system 💖 like, she's reliable, she's the group project member who actually does the work ✨
  • 255 — preempts all other handlers 🔥 she goes FIRST, she does not wait, she is THAT girl, periodt 👑
ngl the jump from 128 to 255 is dramatic and honestly? iconic. pick your number with intention bestie 💅

✨ DESCRIPTION ✨

okay so here's the tea ☕: if a wdd->ops->restart function is provided when watchdog_register_device is called, it will be registered as a restart handler with the priority given here 💫

so basically — you show up with a restart function, the kernel registers it, and whatever priority you handed over via this function is the priority it gets. no takebacks, no renegotiation, that's the deal 🎀 lowkey important, highkey slay 💜
