👑 DESCRIPTION 👑

so basically this function returns the total count of rwstat, and the key detail here is it doesn't care about IO direction at all — no cap, total is total 💀

and here's the part that's lowkey iconic: you can call this function without synchronization and it takes care of u64 atomicity all by itself. she handles her own business, main character energy fr fr 🔥
