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.
Found bugs[edit]
Note that the list is probably incomplete; there were a few bugs found and fixed before we cared to document it here.
