v3: 04: Add check in aio_pending. [Kevin] I tested this series survives the "snapshot + commit" loop reproducer with both bonnie++ and RHEL installation in the guest.
This supersedes the "virtio: Register host notifier handler as external" patch from yesterday. The bug was initially reported by Matthew Schumacher as LaunchPad Bug 1570134, and nicely bisected by Max Reitz. See patch 2 for the analysis.
