💖 drm_gem_release(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're in kernel land today, and yes this page is short but she's IMPORTANT. pull up a chair 🎀

---

✨ NAME ✨

drm_gem_release — release file-private GEM resources 💅

---

🌸 SYNOPSIS 🌸

void drm_gem_release (struct drm_device *dev , struct drm_file
*file_private );

like, that's the whole signature. two pointers, zero drama. 🦋

---

🎀 ARGUMENTS 🎀

• dev — the drm_device that userspace is closing, aka the thing that's like "ok bye" 👋
• file_private — the drm file-private structure that needs to get cleaned up 🧹✨

---

💜 DESCRIPTION 💜

so this one gets called at close time, when the filp is going away. you know that moment. the goodbye moment. 😭

and what does she do? she releases any remaining references on objects held by this filp. that's it. that's the whole job. cleanup queen behavior honestly 👑

ngl this is the "make sure nothing leaks when userspace dips" function. respect her.
