💅 drm_release_noglobal(9)

okay bestie, welcome to the drm_release_noglobal page — it's a kernel API manual moment, from the Kernel API Manual, and it's literally the release method for a DRM file. yes, that DRM. no cap. 🎀

---

✨ SYNOPSIS ✨

int drm_release_noglobal (struct inode *inode , struct file *filp );

like, that's the whole signature. she's short and she knows it. 🦋

---

🌸 ARGUMENTS 🌸

• inode — the device inode. yep, that one. the device-y inode. 📁
• filp — the file pointer. literally a pointer to the file. periodt. 📎

---

💖 DESCRIPTION 💖

okay so here's the vibe: drivers can use this function as their file_operations.release method. like, that's her job. she's the release method. main character energy fr fr.

the way that she works: she frees any resources associated with the open file prior to taking the drm_global_mutex. order matters, bestie — resources go bye-bye before the mutex gets grabbed. iykyk. 🔥

and then, if this is the last open file for the DRM device, she restores the active in-kernel DRM client. iconic behavior honestly. last one out turns the lights back on. 💡✨

---

🫶 RETURN 🫶

she always succeeds and returns 0. that's it. no drama, no errors, just 0. slay. 👑
