get_task_exe_file(9)

✨ get_task_exe_file(9) ✨

okay so welcome to the Kernel API Manual, bestie — this one's a kernel function, section 9, and it's lowkey iconic 🎀

---

💅 NAME

get_task_exe_file — acquire a reference to the task's executable file 🫶

---

🌸 SYNOPSIS

struct file * get_task_exe_file (struct task_struct *task );

---

🦋 ARGUMENTS

• task — the task. that's it. that's the whole argument, no notes 💀

---

🔥 DESCRIPTION

So here's the vibe: this returns NULL if the task's mm (if it even has one) has no associated executable file, or if this is a kernel thread with a borrowed mm — peep the comment above get_task_mm for the whole lore on that one 👀

⚠️ also, the user must release the file via fput — like, you got the reference, now you GOTTA give it back, no cap. not optional. don't leave it hanging, fr fr 😭
