Description Johannes Weiner 2011-03-15 09:28:58 EDT 
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.

Thanks!
