drm_suballoc *sa , size_t size );

three things go in, an int comes out. classic. 🔥

💖 ARGUMENTS 💖

  • sa_manager — pointer to the sa_manager. yes she's a pointer, yes you gotta hand her over, no you can't skip her. 👑
  • sa — The struct drm_suballoc. the actual suballoc star of the show, main character energy fr fr. ⭐
  • size — number of bytes we want to suballocate. how much room do you need? say it with your chest. 📏

🧚 DESCRIPTION 🧚

Try to make a suballocation on a pre-allocated suballoc object of size size. that's the whole bit — it's a try, so don't act surprised if it doesn't always work out, that's literally what the return value is for, iykyk. 💀
