Description Johannes Weiner 2011-03-15 13:28:58 UTC 
With transparent huge pages enabled, the OOM killer may trigger earlier on a memory cgroup close to its limit than it would have with only regular pages.

This is a regression for users that have had a working combination of workload and memory control group configuration prior to THP.

Hello RH,

I have verified this bugzilla on RHEL6.1 Snap4(2.6.32-131.0.1) and found that the test is running fine without any issues.

Thanks!
