kmalloc_obj(9)

✨ NAME ✨

okay so bestie, this is kmalloc_obj(9) from the Kernel API Manual — and its whole thing is allocating a single instance of the given type. one (1) little guy. iconic. no cap. 💅

🎀 SYNOPSIS 🎀

kmalloc_obj (VAR_OR_TYPE , ... );

🫶 ARGUMENTS 🫶

• VAR_OR_TYPE — the variable or type you're allocating. that's the main character of this call. ✨
• ... — optional GFP flags for the allocation. if you don't pass any, it's GFP_KERNEL, periodt. 🌸

💖 RETURN 💖

on success you get a newly allocated pointer to a VAR_OR_TYPE — slay. on failure you get NULL. 😭
