[Qemu-devel] [PATCH v2 0/4] virtio-blk: fix issues with unified virtio-blk request handling |

This series fixes issues recently introduced when unifying virtio-blk
dataplane's request handling with non-dataplane virtio-blk.
The problems include broken memory allocation for dataplane requests and a
performance regression for non-dataplane. See the patches for details.
Stefan Hajnoczi (4):
virtio-blk: avoid dataplane VirtIOBlockReq early free
dataplane: do not free VirtQueueElement in vring_push()
virtio-blk: avoid g_slice_new0() for VirtIOBlockReq and
VirtQueueElement
virtio-blk: embed VirtQueueElement in VirtIOBlockReq
