This patch implements the release of the backend device before calling for the destruction of the userspace component of the blktap device. Without this patch the kernel xen-blkback driver deadlocks with the blktap2 user control plane until the IPC channel is terminated by the timeout on the select() call. This results in a noticeable delay in the termination of the guest and causes the blktap minor number which had been allocated to be orphaned.
