Hi,

If compiling the latest code (8cc1d9743201cb9ae9a5286c898b9d47e318ed46),
the following warning messages are printed.

 $ make
 [snip]
 cgset.c: In function 'usage':
 cgset.c:123: warning: too many arguments for format
 [snip]
 $

This patch fixes too many program name in the usage message of "cgset"
command.

cgset: Change the generation of cgroup

2009-06-29T11:29:16+00:00

- This patch change the system of generating cgroup  to
1/ create one src cgroup
2/ for each input cgroup name cgroup_copy_cgroup
   the name-value data from original one
This method is better because the name-values pairs should not be
parsed several times. And this method will be used in new coption
--copy-from too (the src group will be find in option)

move the part in which src is generated to separate function

libcgroup: Introduce a unload cgroups API

2009-06-22T11:50:09+00:00

This API will unload the cgroups created in the cgroupfs and
unmount and delete the filesystem mount point. The action is
equivalent to what is done currently in service cgconfig stop.

The reason for this API is to make sure we don't end up with a
asymmetric library API subset. Today an application program can
programatically through cgroup_config_load_config() load a
configuration file, but has no means to cleanup (including all
temporarily created groups).

changes from v3
1. Address Jan's comments from http://article.gmane.org/gmane.comp.lib.libcg.devel/1105
changes from v2
1. Fix a leak as noted by Bharata
2. Address Balbir's review comments at
http://article.gmane.org/gmane.comp.lib.libcg.devel/1080
changes from v1
1. Change the name of the function to cgroup_unload_cgroups
2. Change the name of the executatble to cgclear
3. Split out the funtions

This patch adds cgset tool, which sets parameters of controllers
for given cgroup based on input name-variable pairs
- the syntax is:

cgset -r  

-------------------------------------------------
EXAMPLES:
$ cgcreate -g cpuset:test1
$ cgset -r cpuset.cpus=1 test
$ cat ./test/cpuset.cpus
1

$ cgcreate -g cpuset:test1 -g cpuset:test2
$ cgset -r cpuset.cpus=0 test1 test2
$ cat /mnt/cgroups/cpuset/test1/cpuset.cpus
0
$ cat /mnt/cgroups/cpuset/test2/cpuset.cpus
