[libvirt] [RFC PATCH v1 0/7] virCgroup refactor



Hi,

This series is posted for early review.

This series refactors virCgroup. The changes are:

  - virCgroupItem is associated with a cgroup directory. The directory
    is created only when needed, and removed if no one is using it.
  - Anyone using cgroups creates instances of virCgroupItem and maintains
    their lifetime.

Please focus on patch #5, which brings the main change(virCgroupItem),
and qemu part in patch #6, which shows the usage of virCgroupItem(I've not
tested lxc part yet).

Hu Tao (7):
  call virstateCleanup to do the cleanup before libvirtd exits
  include util.h in cgroup.h
  include virterror_internal.h in threads.h
  refactor virCgroupDetectMounts and virCgroupDetectPlacement
  cgroup: refactor virCgroup
  deploy the newly introduced virCgroupItem.
  tests for virCgroup.
