Subject: [Qemu-devel] [PATCH v3 0/4] virtio-blk: fix issues with unified virtio-blk request handling
Date: Wed, 9 Jul 2014 10:05:45 +0200 [thread overview]
Message-ID: <1404893149-27701-1-git-send-email-stefanha@redhat.com> (raw)
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
