----------------
What's the point in defining these TSAN_INTERCEPT_MMAP64 macros? Looks like an unnecessary level of indirection. They are used exactly once, and now I need to modify 3 places in stead of 2 when working with an interceptor.
Please remove TSAN_INTERCEPT_MMAP64 macros and use the condition (e.g. SANITIZER_LINUX) directly. Looks like a net win to me.
