💅 drm_gem_shmem_object_unpin(9) — like, the Kernel API Manual, bestie 💅

okay so real talk, we're in the Kernel API Manual rn and this page is all about drm_gem_shmem_object_unpin(9). she's a tiny little wrapper function and honestly? she ate. let's get into it ✨

🎀 NAME 🎀

drm_gem_shmem_object_unpin — the GEM object function for drm_gem_shmem_unpin(). no cap, that's literally her whole job description 🫶

---

🌸 SYNOPSIS 🌸

void drm_gem_shmem_object_unpin (struct drm_gem_object *obj );

that's it. that's the whole signature. short and iconic 💅

---

🦋 ARGUMENTS 🦋

• obj — the GEM object. yes bestie, that's the one. she's a struct drm_gem_object * and she's the main character of this function 🙈

---

⭐ DESCRIPTION ⭐

so here's the vibe: this function wraps drm_gem_shmem_unpin. that's it, that's the whole lore. 🧚

drivers that employ the shmem helpers should use it as their drm_gem_object_funcs.unpin handler. like, that's the assignment. that's where she belongs. iykyk 🔥

ngl it's giving "middle management" but in the best way possible — she exists so your driver's unpin handler has somewhere cute to live 💖
