kthread_probe_data(9)

okay bestie, welcome to kthread_probe_data(9) from the Kernel API Manual 💅 this is the speculative version of kthread_data(), and we're gonna get you through it, no cap ✨

💖 NAME 💖

kthread_probe_data — speculative version of kthread_data() 🦋

✨ SYNOPSIS ✨

void * kthread_probe_data (struct task_struct *task );

🎀 ARGUMENTS 🎀

• task — the possible kthread task in question, bestie 🫶

🦋 DESCRIPTION 🦋

okay so task could be a kthread task 👀 Return the data value specified when it was created, if it's accessible. If task isn't a kthread task, or its data is inaccessible for any reason, you get NULL back — that's the whole tea ☕

This function requires that task itself is safe to dereference, periodt. Like, that's not optional, bestie 😭
