virtio-scsi-dataplane: Code to run virtio-scsi on iothread
This implements the core part of dataplane feature of virtio-scsi. A few fields are added in VirtIOSCSICommon to maintain the dataplane status. These fields are managed by a new source file: virtio-scsi-dataplane.c. Most code in this file will run on an iothread, unless otherwise commented as in a global mutex context, such as those functions to start, stop and setting the iothread property. Upon start, we set up guest/host event notifiers, in a same way as virtio-blk does. The handlers then pop request from vring and call into virtio-scsi.c functions to process it. So we need to make sure make all those called functions work with iothread, too. Signed-off-by: NFam Zheng <famz@redhat.com> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>
