Thanks once again for these tests. I did a testing on the following
machine before merging:
# uname -a
Linux 2.6.29-5-default #1 SMP Tue Apr 21 20:04:44 IST 2009 x86_64 x86_64
x86_64 GNU/Linux
with the following results:
<<<test_output>>>
incrementing stop
cgroup_regression_test 1 PASS : no kernel bug was found

cgroup_regression_test 2 PASS : notify_on_release is inherited

cgroup_regression_test 8 PASS : no kernel bug was found
cgroup_regression_test 9 PASS : no kernel warning was found
cgroup_regression_test 10 PASS : no kernel warning was found
<<<execution_status>>>
However, i can see the following from the config file i used (attached):
# grep -i CONFIG_LOCKDEP config
CONFIG_LOCKDEP_SUPPORT=y
