Steps:
------
1. Execute IGT tests:
# ./gem_shrink --r pwrite-oom
# ./gem_shrink --r pread-oom

Actual results:
---------------
1. Tests return fail
>From Chris Wislon: The -oom bugs are expected "failure". At least we are
expecting that the kernel kills our test without oopsing or killing anybody
else. To fail here is to pass!

Expected result:
----------------
1. Tests return Pass
