drm_file_get_master(9)

🎀 drm_file_get_master(9) 🎀

okay bestie, this page is straight from the Kernel API Manual and it's giving “tiny refcount helper with main character energy.” Let’s go. ✨

💖 NAME 💖

drm_file_get_master — reference &drm_file.master of @file_priv

🌸 SYNOPSIS 🌸

struct drm_master * drm_file_get_master (struct drm_file *file_priv );

🦋 ARGUMENTS 🦋

• file_priv — the DRM file private 🫶

✨ DESCRIPTION ✨

okay so here's the tea: drm_file_get_master increments the reference count of file_priv's drm_file.master and returns the drm_file.master. Slay. If file_priv has no drm_file.master, it returns NULL. No cap.

💅 important bestie: master pointers returned from this function should be unreferenced using drm_master_put. Don't ghost the cleanup, fr fr.
