get_mm_exe_file(9) — Kernel API Manual 💅

okay bestie, welcome to the Kernel API Manual page for get_mm_exe_file(9) — the little function that’s all about grabbing the executable file tied to an mm. ✨

---

🌸 NAME 🌸

get_mm_exe_file — acquire a reference to the mm’s executable file. That’s it, that’s the mission, and honestly it’s giving very specific main character energy. 🎀

---

🦋 SYNOPSIS 🦋

struct file * get_mm_exe_file (struct mm_struct *mm );

---

🎀 ARGUMENTS 🎀

• mm — the mm of interest. Yep, that’s the mm you’re checking, bestie. 🫶

---

💖 DESCRIPTION 💖

So here’s the tea: it returns NULL if mm has no associated executable file. No exe file? You get NULL, periodt. 😭

And the user must release file via fput — that part is not optional, okay? Don’t be out here leaving files hanging. 💅

🚨 Reminder: user must release file via fput. Very much a “do not forget this” situation.
