Alexei Starovoitov dccb4a9013 bpf: Prepare bpf_mem_alloc to be used by sleepable bpf programs. 
Use call_rcu_tasks_trace() to wait for sleepable progs to finish.
Then use call_rcu() to wait for normal progs to finish
and finally do free_one() on each element when freeing objects
into global memory pool.
