+* Description:
+* This testcase builds into the ltp framework to verify that kernel is
+* PID NS enabled or not.
+*
+* Verify that:
+* 1. Verify that the kernel version is 2.6.24.
+* 2. Verify that clone() function return value.
+*
+* Test Name: check_pidns_enabled
+*
+* Test Assertion & Strategy:
+* Check that the kernel version is 2.6.24 and clone returns no failure after passing
+* the clone falg as CLONE_NEWPID.
