kthread_should_park(9)

💖 kthread_should_park(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — this one's short, sweet, and honestly kind of a vibe. Let's get into it 🫶

---

🌸 NAME 🌸

kthread_should_park — should this kthread park now? 🚗💨

---

✨ SYNOPSIS ✨

bool kthread_should_park (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments, bestie. none. zero. the void is voiding 💀

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — when someone calls kthread_park on your kthread, your thread gets woken up, and this function will return true. that's your signal, your little notification ping 🔔.

and then?? you do the necessary cleanup, and you call kthread_parkme. that's the whole assignment. slay 💅

it's giving very similar to kthread_should_stop, lowkey — but the difference is iconic: this one keeps the thread alive and in a park position 🅿️. think of it as your thread pulling into a parking spot, engine still running, just chillin' ✨

and then kthread_unpark "restarts" the thread and calls the thread function again 🔁. it's a whole comeback arc, main character energy fr fr 👑
