Hi Naresh! Thank you for the report! The interaction between ptrace and freezer is complicated (as ptrace in general),so there are known cases when spurious cgroup transitions (frozen <-> non frozen <-> frozen ) can happen. Does it create any difficulties? If so, I'll send a diff to ignore the result of this test for now.
