The runlibcgrouptest.sh will now whine when script is started by non-root
user. Root permissions are needed to create directories and mount the cgroups
there.

Automake's 'make check' executes runlibcgrouptest.sh automatically. It
interprets exit code '77' as 'skip the test' and it is not counted as failure.
Also the script should return nozero exit code != 77 when some test fails.

runlibcgrouptest.sh should be executable, so 'make check' can execute it.

Sometimes on some machines, encounterd an issue of getting the controllers
information in reverse order. So keeping the uniformity for future.

This patch makes the use of controllers available from script more generic.
All possible controllers in Linux kernel are to be kept as enum parameters
and a corresponding mapping is done in both, the script and binary. The
testcases are no more hardcoded with respect to controllers. The function
set_controller() need to be updated with respect to the controllers and
control file.
The challenges yet to be solved are:
(1)Choosing appropriate control file
(2)Choosing appropriate control value dynamicaly.
Thoughts are most welcome.

The following patch adds support for a dynamical check of controllers and
choosing two of them, which are enabled in the kernel. I have given preference
to the cpu and memory controller if they exist.
I will pass these mounted controllers to the c file(will send implementation in
a next patch) and thus the c file will have no hard coding with respect to any
controller. The reason of chosing script for this part is
1. easy to implement
2. otherwise there wont be any use of script :)
One of my doubts is:
Few controllers(e.g. devices) seems not to be having a control file. Please help
me in finding the control file for each controller. Any link to documentation?
This info I need in the c file.
As per my knowledge the control files are:
*****************************
controller control_file
*****************************
cpu cpu.shares
memory memory.linit_in_bytes
debug
devices
ns
cpuacct
cpuset
Also what type of values can be written to those control files?
I need to take care before i write something stupid to a control file.
Please review the patch and give your valuable comments.

Hi,
This patch does cleanups in test script.

Hi
The shell script as expected does not do a non null check using -n option
as i observed. hence changing the logic as below.

This patch modifies the script to handle multiple mounts. The earlier
functions are modified and new ones are added. There is still some hard
coding with respect to the number of mountpoints and controllers. I will
update this code part once I get an idea of a better design.

libcgroup: framework for libcgroup testcases
This Patch creates the basic infrastructure for libcgroup testcases. This
patch adds a script which runs the binary(C) file. The script does all the
environment setup to run the tests and passes this info to the C file through
command line arguments. The binary runs the test cases calling the API's
in different environment conditions. The Makefile compiles the test. The top
level Makefile.in is edited to support
make test
make testclean
The script runs this binary total 3 times, each time with diff varaible.
FS_MOUNTED=0 # cgroup fs not mounted
FS_MOUNTED=1 # cgroup fs mounted
FS_MOUNTED=2 # cgroup fs mounted at multiple points
