Subject: virtio: do not set is_external=true on host notifiers
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=03d7162a21e60d87cfa39a8d078c784487fa5f30;p=qmiga%2Fqemu.git

virtio: do not set is_external=true on host notifiers

Host notifiers can now use is_external=false since virtio-blk and
virtio-scsi no longer rely on is_external=true for drained sections.
