Hi Andrew, this small patchset addresses a possible livelock when OOM killer tries to kill a frozen task. The issue has been reported by Konstantin Khlebnikov at https://lkml.org/lkml/2011/8/23/45. The first patch addresses a possible issue in lguest which calls try_to_freeze with user context and then continues with other work after it returns from the fridge. The second patch addresses the issue by thawing the frozen task in the oom kill path.
