freeze_processes(9)

🌸 NAME 🌸

okay so freeze_processes(9) — from the Kernel API Manual — is literally the “everybody into the refrigerator” signal for user space processes. It signals user space processes to enter the refrigerator. The current thread will not be frozen. And bestie, this part matters: the same process that calls freeze_processes must later call thaw_processes. No cap. 💅

✨ SYNOPSIS ✨

int freeze_processes (void );

🧊 ARGUMENTS 🧊

• void — no arguments. None. Zero. Nada. It’s giving “takes no args and knows it.” 🫶

💖 DESCRIPTION 💖

On success, it returns 0. Slay.

On failure, it returns -errno, and the system is fully thawed. That’s the whole vibe check: failure leaves things fully thawed. 🧊✨

🦋 SEE ALSO 🦋

• Kernel file ./kernel/power/process.c
• freeze_kernel_threads(9)

mwah 💋 this freeze_processes(9) page comes from ./kernel/power and is dated October 2026 — that’s the footer, bestie, and it’s iconic. 🫶
