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

Hello, This is v2 of the virtio-pstore work. In this patchset I addressed most of feedbacks from previous version. Limiting disk size is not implemented yet. * changes in v2) - update VIRTIO_ID_PSTORE to 22 (Cornelia, Stefan) - make buffer size configurable (Cornelia) - support PSTORE_TYPE_CONSOLE (Kees) - use separate virtqueues for read and write - support concurrent async
