POSIX defines the values of standard in, out, and error as 0, 1, and 2 constants. So this patch is correct but it doesn't do anything useful. This is something compiler can optimize (but speed doesn't even matter here). Please try to focus on patches that fix bugs, add features, or otherwise add value - it takes the community time to review, test, and merge patches. Thanks, applied to my net-next tree: https://github.com/stefanha/qemu/commits/net-next Stefan
