Hi,

could this be this one?

commit 47a150a4bbb06e45ef439a8222e9f46a7c4cca3f
Author: Paolo Bonzini <address@hidden>
Date:   Thu Jan 10 15:49:08 2013 +0100

    virtio-scsi: abort in-flight I/O when the device is reset

    When the device is reset, the SCSI bus should also be reset so
    that in-flight I/O is cancelled.
