Interesting, zdtm also works for me, but I am not able to dump other
processes like: https://lisas.de/~adrian/memcmp.c

criu dump -t `pidof memcmp` -j -vvvv

Both the criu from my RPM and from the git checkout master does not
work. zdtm works from git master.

This zdtm test hangs for me:

# ./zdtm.py run -t zdtm/static/cgroup_stray

Not sure if it is the same error as on the command-line.
