[PATCH 0/2] virtio-blk: improve handling of DMA mapping failures
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.
