We have the [https://ci.openvz.org/job/CRIU/view/All/job/CRIU-linux-next/ CRIU-linux-next] job to check all kernel changes before they move into the upstream kernel.
+
We have implemented [[Continuous integration#Kernel testing]] to check if any recent kernel changes break CRIU, to catch those before they appear in the vanilla kernel. This article documents Linux kernel bugs found using this method.
