Kernel bugs

We have implemented Travis CI setup (and were using Jenkins before) to check if any recent kernel changes break CRIU — before they appear in the vanilla kernel.
Found bugs
This table lists the linux-next kernel bugs found using CI.
Note that the list is incomplete; there were about a dozen bugs found and fixed before we started documenting it here.
