trace_sched_prepare_exec(9)

💅 trace_sched_prepare_exec(9) — Kernel API Manual 🎀

✨ NAME ✨

trace_sched_prepare_exec — called before setting up new exec. That's the whole vibe, bestie: it's the pre-exec checkpoint, the “before” pic of the exec switcheroo. 📸

🌸 SYNOPSIS 🌸

void trace_sched_prepare_exec (struct task_struct *task , struct
       linux_binprm *bprm );

🎀 ARGUMENTS 🎀

• task — pointer to the current task 👀. Like, the task that's still living its old-exec life at this exact moment.
• bprm — pointer to the linux_binprm used for the new exec 🌱. This is the new-exec blueprint, basically.

🦋 DESCRIPTION 🦋

Okay so this one is called before flushing the old exec, and the way that task is still unchanged here? Iconic. But it's also the point of no return during the switch to the new exec. 🚨 At the point it is called, the exec will either succeed, or on failure terminate the task. No soft launch, no “we'll fix it in post” — it's giving final boss energy. 💀

Also see the "sched_process_exec" tracepoint, which is called right after task has successfully switched to the new exec. ✨ So this page is the pre-game, and that tracepoint is the after-party. 🎉
