[CRIU] [PATCH] zdtm/cgroup_yard: create a test cgroup yard from the post-start hook

[Andrei Vagin]

Right now, it is created from the pre-dump hook, but
if the --snap option is set, the test fails:
$ python test/zdtm.py run -t zdtm/static/cgroup_yard -f h --snap --iter 3
...
Running zdtm/static/cgroup_yard.hook(--pre-dump)
Traceback (most recent call last):
  File zdtm/static/cgroup_yard.hook, line 14, in <module>
    os.mkdir(yard)
OSError: [Errno 17] File exists: 'external_yard'
