It is not a simplification, it is just code motion. Further at least to my eyes adding multiple exit points and setting the same value in two different places actually obscures what the functions are doing. If we could talk about speeding up the performance of the stat system call I think there would be a point in mucking with these functions. As it is I think it is I think merging your patch will just make it more difficult to understand what the code is doing in the future, with no benefit except a reduction in line count.
