      dump: use freezer cgroup to seize processes (v4) · 8ea02038
      Andrey Vagin authored 
      Without using a freezer cgroup, we need to do a few iterations to catch
all tasks, because a new tasks can be born. If new tasks appear faster
than criu collects them, criu fails. The freezer cgroup allows to
solve this problem.

We freeze the freezer group, then attaches to tasks with ptrace and thaw
the freezer cgroup. We suppose that all tasks which are going to be
dumped in a specified freezer group.

v2: fix comments from Christopher

      seize: set cr_errno in collect_pstree · 69b093ad
      Andrew Vagin authored 
      Before cr_errno was called from open_pid_proc(), but
now it isn't called if a root task doesn't exist.
