> ProcfsBasedProcessTree in Node manager calculates memory used by a process
> tree by parsing {{/etc/<pid>/smaps}}, where it calculates {{min(Pss,
> Shared_Dirty) + Private_Dirty + Private_Clean}}. Because not {{mlocked}}
> private clean pages can be reclaimed by kernel, this should be changed to
> calculating only {{Locked}} pages instead.
