-------------------------------------------------------

But the case "cgroup_fj" does not need "-lcontrollers" when building.
So in my patch, i deleted "-lcontrollers" in 
testcases/kernel/controllers/Makefile.inc 
and added it to testcases/kernel/controllers/memctl/Makefile because the case 
"memctl" 
need it. 
All other cases in testcases/kernel/controllers/ build well too when my patch 
merged.
