Hi,

I found the following warning at cpuset_syscall_test.c.

===============
make[5]: Entering directory `/root/ltp/ltp-old/testcases/kernel/controllers/cpuset/cpuset_syscall_test'
gcc -g -O2 -g -O2 -fno-strict-aliasing -pipe -Wall  -I/root/ltp/ltp-old/testcases/kernel/include -I../../../../../include -I../../../../../include
-L/root/ltp/ltp-old/testcases/kernel/controllers/cpuset/cpuset_syscall_test/../cpuset_lib
-L/root/ltp/ltp-old/testcases/kernel/controllers/cpuset/cpuset_syscall_test/../../libcontrollers -L../../../../../lib  cpuset_syscall_test.c   -lltp -lcpu_set
-lcontrollers -lltp -o cpuset_syscall_test
cpuset_syscall_test.c: In function 'main':
cpuset_syscall_test.c:254: warning: control reaches end of non-void function
make[5]: Leaving directory `/root/ltp/ltp-old/testcases/kernel/controllers/cpuset/cpuset_syscall_test'
===============

This warning appears because it doesn't have "return <num>" in main().
The attached patch will fix it.
