dump_tasks(9)

💅 dump_tasks

okay so welcome to the Kernel API Manual, bestie — this is the page for dump_tasks(9), and it's lowkey iconic. 🫶

🌸 NAME 🌸

dump_tasks — dump current memory state of all system tasks. Periodt. 💅

🦋 SYNOPSIS 🦋

void dump_tasks (struct oom_control *oc );

It's void, bestie — no return value to catch. ✨

🎀 ARGUMENTS 🎀

• oc — pointer to struct oom_control. That's the one and only arg, and yes, it's a pointer. 🎀

✨ DESCRIPTION ✨

Okay so dump_tasks dumps the current memory state of all eligible tasks. Like, it's giving full memory-state recap energy. 💅

The vibe check has rules, though: tasks not in the same memcg, not in the same cpuset, or bound to a disjoint set of mempolicy nodes are not shown. No cap. 🫶

The state info it includes is: the task's pid, uid, tgid, vm size, rss, pgtables_bytes, swapents, oom_score_adj value, and name. Literally all of those deets. 🌟
