[Devel] privvmpages problem in 2.6.15beta

[Miroslav Ruda]

Hello,

  I'm testing 2.6.15-025stab014-default on AMD64 machine and I have some 
problems with privvmpages. It seems to me that value of privvmpages is nevere 
decreased.
This is current situation in one VPS:

never changed back when program finish. Is it know bug or my misunderstanding
of privvmpages?
