My workmate Miao Xie (miaox@cn.fujitsu.com) has created some testcases for 
cgroup's subsystem "cpu" in the last year. And, He catched some kernel bugs 
through these testcases. So we think you glad to push them into LTP.

There are total 22 testcases that have been added. These testcases contain 
the basis operation test and part functionality test of cpu controller.

How to run this test:
	# runltp -f controllers

Result:
cpuctl_test_fj    1  PASS  :  case1    PASS

+TEST SUITE:
+
+The directory cpuctl_fj contains the tests related to the cpu controller.
+
+Cpu controller is a mechanism for assigning cpu resource (in percent) to 
+a set of tasks.
+
+There are total 22 testcases that have been added. These testcases 
+contain the basis operation test and part functionality test of cpu 
+controller.
+
+NOTE: the test can be run by root only.
+
+TESTS AIM:
+
+The aim of the tests is to test the functionality of cpu controller.
+
+FILES DESCRIPTION:
+
+run_cpuctl_test_fj.sh
+--------------------
+This script runs all the 22 testcases.
+
+cpuctl_fj_cpu-hog.c
+--------------------
+The program does a calculation of sqrt till catched a signal.
