Hi Dhaval,
Today i tried 2 more scenario requested by you on -tip kernel:
1> mount cpu on cgroup & other susbsystems ( ns, cpuset,freezer...
except cpu) on cgroup1 e.g:.
/root/lxc on /cgroup type cgroup
(rw,ns,cpuset,freezer,devices,memory,cpuacct,net_cls)
none on /cgroup1 type cgroup (rw,cpu)
Result: I am able to create container ( no crash after "lxc-execute
..." command execution).
2> mount cpu,ns on cgroup
[root@x335a ~]# mount
none on /cgroup type cgroup (rw,ns,cpu)
[root@x335a ~]# lxc-execute -n foo2 -f /etc/lxc/lxc-macvlan.conf /bin/bash
Result : The system crash with following trace once i execute
lxc-execute command:

Evening i am going to try 3rd scenario:
- Enable CONFIG_PROVE_LOCKING and then execute above scenario once
again.
Hope above result will help you to debug further.
