...s arguable. Since commit f7728002c1c7 it the dma mapping has failed returns -ENOMEM and not -EIO, and thus we have a recoverable failure that ain't virtqueue full. So I lean towards to a fixes tag that references that commit, although it ain't broken. Alternatively one could say 'Fixes: e467cde23818 ("Block driver using virtio.")', if the aforementioned assumption shouldn't have made in the first place. --- drivers/block/virtio_blk.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/drivers/block/virtio_blk.c b/drivers/block/virtio_blk.c index 54158...

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.
