    Description

      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.
