My specific area of expertise in Linux kernel is security/tomoyo/ directory.
What I could contribute with other areas is to pay attention to potential
possibilities. But I'm such outsider about other areas that I can't
differentiate the page allocator proper from the OOM killer layer.

Excuse me for focusing on the wrong issue, but I will likely unconsciously
make the same mistake again. Please ignore or point out when I made mistakes.
