If you see xstate_size larger than your kernel stack size, VSO is likely active. If you have spent any time on VA
FPState VSO is a brilliant, invisible piece of kernel engineering that makes modern x86 systems more memory-efficient without sacrificing security. If you are not writing kernel code or debugging kernel crashes, you will never interact with it directly. If you are a kernel developer, understanding VSO is essential to avoid subtle corruption bugs and stack overflows on AVX-512 workloads.
