Subject: Linux kernel : sysctl registering table under same proc name (path)
 gives warning and call trace while unregistering

Hello there,

I am creating a sysctl kernel module to register 2 hierarchy under
same proc name. For e.g.

  my_net
  |          |
net1  net2
 |         |
t1        t2

So, I used register_sysctl_paths() API. Everything works fine when
registering the sysctl tables net1 net2 under path name my_net.

Problem is when unregistering the tables dmesg shows kernel tainted
warning and a call trace.

Here, is pastebin link to the warning message http://pastebin.com/NfLQhikJ

Here is pastebin link to module source http://pastebin.com/jSfPW5Y5

Kindly, please help me to resolve this panic.

Thanks,
Chaitanya
