okay so we're in the Kernel API Manual, and this page is about sprint_symbol_build_id — yes, the name is a mouthful, but she's iconic. 🫶

✨ DESCRIPTION ✨

okay so this function looks up a kernel symbol with address and stores its name, offset, size, module name, and module build ID to buffer if possible. If no symbol was found, it just saves its address as is. No cap. 😭
