[Qemu-devel] [PATCH v3 0/4] virtio-blk: fix issues with unified virtio-blk request handling

[Stefan Hajnoczi]

v3:
 * Add Christian's Tested-by: [Kevin]
 * Resolved merge conflict in Patch 4 with qemu.git/master [Kevin]

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
