rcu_read_lock() should be fine. From Eric's patch at
2.6.17-mm2 - proc-remove-tasklist_lock-from-proc_pid_readdir.patch
The patch mentions that "We don't need the tasklist_lock to safely
iterate through processes anymore."
Containers V10 includes an iterator interface for listing the member
tasks of a container, which avoids scanning the entire tasklist.
Downside is that it currently requires taking a read_lock on a global
lock, but I hope to improve on that in the future.
