Sorry, this was a reply to the wrong patch hunk.

The css_get() in mem_container_create() is the unnecessary one.

Also, rather than doing something like:

mem_container_from_cont(task_container(p, mem_container_subsys_id))

you'd be better off defining a similar wrapper to
mem_container_from_cont() called mem_container_from_task() that uses
task_subsys_state() rather than container_subsys_state() - you'll save
a few indirections.
