The aio_disable_external() API is a solution for stopping I/O during critical sections. The newer BlockDevOps->drained_begin/end/poll() callbacks offer a cleaner solution that supports the upcoming multi-queue block layer. This series removes aio_disable_external() from the virtio-scsi emulation code.
Patch 1 is a fix for something I noticed when reading the code. Patch 2 replaces aio_disable_external() with functionality for safe hot unplug that's mostly already present in the SCSI emulation code.
