Ravikiran G Thirumalai 2dd0ebcd2a [PATCH] Avoid taking global tasklist_lock for single threadedprocess at getrusage() ...

Avoid taking the global tasklist_lock when possible, if a process is single
threaded during getrusage().  Any avoidance of tasklist_lock is good for
NUMA boxes (and possibly for large SMPs).  Thanks to Oleg Nesterov for
review and suggestions.
