There is no behavior change, it is just more readable to use -1 to mean don't touch this. Please note that if the GID is not mapped in the userns, by using -1 for that no error is returned. We just avoid dealing with it completely, as we want here. Signed-off-by: Rodrigo Campos <rodrigoca@microsoft.com>
