Hello, This patchset is a proof of concept of virtio-pstore idea [1]. It has some rough edges and I'm not familiar with this area, so please give me feedbacks and advices if I'm going to a wrong direction. It started from the fact that dumping ftrace buffer at kernel oops/panic takes too much time. Although there's a way to reduce the size of the original data, sometimes I want to
