[CRIU] Cannot run zdtm.py script, flock problem

[Rodrigo Bruno]

Hi,

I was trying to run tests using the zdtm.py script.

However, when running "./zdtm.py run -a":

flock: ./zdtm_mount_cgroups: Text file busy
Traceback (most recent call last):
  File "./zdtm.py", line 1403, in <module>
    tst.available()
  File "./zdtm.py", line 436, in available
    subprocess.check_call(["flock", "zdtm_mount_cgroups", "./zdtm_mount_cgroups"])
  File "/usr/lib/python2.7/subprocess.py", line 540, in check_call
    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['flock', 'zdtm_mount_cgroups', './zdtm_mount_cgroups']' returned non-zero exit status 69

This problem seems to happen because flock is trying to lock the script it is going
to run.

Has anyone got the same problem?

Is this lock important?

I'm able to run all tests I if remove the flock command.

cheers,

rodrigo
