💅 kthread_fre..._should_stop(9)

okay bestie, this one is straight from the Kernel API Manual, and it’s all about checking in on a freezable kthread. 🧊✨

🌸 NAME 🌸

kthread_freezable_should_stop — should this freezable kthread return now? 👀

✨ SYNOPSIS ✨

bool kthread_freezable_should_stop (bool *was_frozen );

🫶 ARGUMENTS 🫶

• was_frozen — optional out parameter, indicates whether current was frozen. 🧊💖

🧊 DESCRIPTION 🧊

okay so this is literally the kthread_should_stop for freezable kthreads, and it will enter the refrigerator if necessary. no cap. 🧚‍♀️

This function is safe from kthread_stop / freezer deadlock, and freezable kthreads should use this function instead of calling try_to_freeze directly. periodt. 💅🔥
