Since musl is using clone3 internally and no longer exports the __NR_fstat/newfstatat macros, that part is fine. The clone() one still isn't correct I think, as the mainline kernel does not yet support the emulation with a zero-length stack length. Once we add that part, musl should be fine, but then the __NR_clone definition is mismatched, as the kernel won't provide that call to user applications any more. Arnd
