libcgroup: Add test cases for new get_task API
This is the test case for the new API. This test takes one argument, the group name. Sample run on my system with this test case returns, [dhaval@gondor tests]$ ../libtool --mode=execute ./walk_task a Printing the details of groups a Pid is 6092 Pid is 11315 Pid is 11318 Pid is 11319 Pid is 11324 Pid is 13234 [dhaval@gondor tests]$ Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com> Acked-by: Balbir Singh <balbir@linux.vnet.ibm.com> Acked-by: Bharata B Rao <bharata@linux.vnet.ibm.com>
