If it happens again I'll let you know. I still have to find what cause it in another combinations of vm patches. Andrew, now that you've the testcase could you test the -mm tree, and see if happens there, some -mm patch is one of the diffs between the working tree and the non-working one. However now I'll repeat all tests, if they works all flawlessy today I will be very annoyed, since the thing was definitely not swapping at all yesterday, no matter how long I awaited. Now I start to wonder if kbuild may have screwed my kernel, effectively it was a development tree, I don't run make distclean anymore in between the kernel compiles (I almost don't feel the need of ccache anymoe ;), but maybe I'm wrong trusting the buildsystem can be smart enough.
