Unable to obtain the complete function call stack of `__memset_avx2_erms`.

When I use stackcount and flamegraph to capture the flame graph of the physical memory allocation function, I cannot obtain the complete function call stack of `__memset_avx2_erms`. Please tell me how to solve it. I have used the -g compilation option.


Start by reproducing the physical memory allocation profile with the mentioned stackcount and flamegraph tools, using the provided image and the __memset_avx2_erms symbol as the focus. Trace how stack collection handles this function and verify the result against a complete call stack; done means the flame graph includes the expected callers.
