Thanks for your review, I will fix the error handling. Please also see
my comments on create vs populate.

I want to use the cgroup directory name for the kernel thread. If I do
that in create() instead of populate, I would have to add more changes:
1. pass dentry to the create function since that is called before
  cgroup_create_dir()
2. skip the dummy root as part of the initialization.
So I chose to use populate, are there any issues with the functionality?
