setgid first, setuid second
Setting a new effective gid requires privileges. We must set the gid
while we potentially still have superuser privileges. Otherwise
setgid(2) fails because we've already changed to an unprivileged uid.
Here is a test case:
[global]
rw=read
directory=tmp
size=512m
buffered=0
[file1]
uid=1000
gid=1000
Without this patch fio will fail when invoked by root.
