Subject: vm commit in atop utility steadilly grows (latest mainline kernel from git)

Yesterday, I have noticed that vmcom steadilly grows (it was 7TB before
I noticed). I compile kernel every day or two after git pull.
Rebooted and then watched atop, vmcom constantly grows.
Didn't notice any of running processes to allocate.
Booted in 3.12.8 kernel and everything is back to normal.
Since this is pretty noticable, I guess that this is caused by commit
between rc8 release and now, not sure.
Machine is i5 3570k, motherboard asus maximus gene v.

Hm, I don't know what happened, perhaps I miscompiled but after
todays git updates and recompile problem is no more.
