SUSPENDSCHED(9)

SUSPENDSCHED(9) 💅 Kernel Developer's Manual 💅

okay bestie, this is the suspendsched(9) page and it’s lowkey iconic. let’s get into it ✨

🎀 NAME 🎀

• suspendsched — suspend the scheduler

✨ SYNOPSIS ✨

#include <sys/proc.h>
#include <sys/sched.h>

void
suspendsched(void);

🌸 DESCRIPTION 🌸

so suspendsched() literally suspends the operation of the scheduler. the way it does that? by stopping all non-system processes which are on the run queue or the sleep queue. no cap 🫶

⚠️ bestie, huge caveat: the suspendsched() function must not be called with the scheduler lock held. like, do not do it. it’s giving “read the room” energy 💀
