🎀 drm_pagemap_zdd_get(9) 🎀

okay so welcome to the Kernel API Manual entry for drm_pagemap_zdd_get(9), bestie. This one is short, sweet, and extremely "tiny ref-count bump" coded. 💅

✨ NAME ✨

drm_pagemap_zdd_get — get a reference to a zdd structure.

🌈 SYNOPSIS 🌈

struct drm_pagemap_zdd * drm_pagemap_zdd_get (struct drm_pagemap_zdd
       *zdd );

🧚 ARGUMENTS 🧚

• zdd — pointer to the zdd structure. That’s the whole argument, no cap. 🫶

💖 DESCRIPTION 💖

So this function increments the reference count of the provided zdd structure. That’s it. A little ref-count glow-up, and honestly? Iconic. ✨

🔥 RETURN 🔥

A pointer to the zdd structure. It hands you back a pointer to the zdd structure, like “here bestie, have this.” 🎀
