drm_fb_release(9)

💅 drm_fb_release — like, the Kernel API Manual page you actually wanna read

okay so bestie, welcome to drm_fb_release, straight out of the Kernel API Manual ✨ this is a little cleanup function and honestly it's giving "end of the group hangout, everybody go home" energy 🫶

---

🌸 NAME 🌸

drm_fb_release — remove and free the FBs on this file, periodt 💅

---

✨ SYNOPSIS ✨

void drm_fb_release (struct drm_file *priv );

---

🎀 ARGUMENTS 🎀

• priv — the drm file for the ioctl. that's the whole vibe, it's just the file you're operating on 🦋

---

💖 DESCRIPTION 💖

Destroy all the FBs associated with filp. all of them. not some, not a few — every single one, gone 🔥

Called by the user via ioctl. so like, this isn't you calling it, the user pokes the ioctl and it comes through here 🧚

---

🌈 RETURN 🌈

Zero on success, negative errno on failure. that's it, that's the whole scoring system: 0 you ate 👑, negative errno something went sideways 😭
