💅 drm_gem_shmem_unpin(9) 💅

okay bestie, welcome to the Kernel API Manual, this one's all about drm_gem_shmem_unpin and honestly it's a whole mood. it's short, it's sweet, it's giving "one job and she does it" energy. let's get into it 🫶

---

✨ NAME ✨

drm_gem_shmem_unpin — unpin backing pages for a shmem GEM object, no cap 💖

---

🌸 SYNOPSIS 🌸

void drm_gem_shmem_unpin (struct drm_gem_shmem_object *shmem );

like, that's the whole signature. she's void, she takes one pointer, she does not return anything. iconic behavior honestly 👑

---

🦋 ARGUMENTS 🦋

• shmem — the shmem GEM object. that's it, that's the arg. she's your main character object and you're handing her over 💅

---

🎀 DESCRIPTION 🎀

so here's the tea, bestie: this function removes the requirement that the backing pages are pinned in memory. that's the whole thing. that's the vibe.

like if you previously said "hey these pages need to stay put," this is the girl who comes along and goes "okay, they can move again, we're done here" ✨ lowkey important, highkey simple.

ngl this one is just the unpin. nothing else. no extra lore, no secret side quests. don't overthink her 🧚
