FWIW, I have some userspace code that indeed wants exactly this: https://github.com/GNOME/libglnx/blob/36396b49ad6636c9959f3dfac5e04d41584b1a92/glnx-fdio.c#L232 So if we add this, I'd presumably change the code to try it and fall back on EINVAL as usual? -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
