Two patches are handling new edge cases introduced by doing DMA mappings (which can fail) in virtio core.
I stumbled upon this while stress testing I/O for Protected Virtual Machines. I deliberately chose a tiny swiotlb size and have generated load with fio. With more than one virtio-blk disk in use I experienced hangs. The goal of this series is to fix those hangs.
