Hi Jan,

Thanks for reviewing! I have another question: I think when
"overcommit_memory" being set to 1, mmap() will always succeed. It's
that correct? I read the code of kernel, looks like in
__vm_enough_memory(), if sysctl_overcommit_memory == OVERCOMMIT_ALWAYS,
it will always return 0. So I think in oom01.c, we should call the
testoom() as testoom(0, 0, 0, 1).


Thanks.
