* cgset: Change the generation of cgroupIvana Varekova2009-06-291-43/+74
| | | | | | | | | | | | | | | - 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 Signed-off-by: Ivana Varekova <varekova@redhat.com> Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com>

* libcgroup: Introduce a unload cgroups APIDhaval Giani2009-06-222-1/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com> Acked-by: Balbir Singh <balbir@linux.vnet.ibm.com>

* Cleanup: Integrate similar code to cgroup_get_uid_gid_from_procfs().Ken'ichi Ohmichi2009-06-081-84/+3
| | | | | | | | | | | | | | CHANGELOG of v2.1: ================ * Rebase the patch for commit '340feae163c4797a6cb1247b3812c1ccdc52fa41'. There are some similar functions for getting process's data (uid, gid) from /proc/<pid>/status file, so this patch integrates these functions into one cgroup_get_uid_gid_from_procfs().
