Nowaday SCSI drivers in guests are able to align UNMAP requests before
sending to the device. Right now QEMU provides an ability to set
this via "discard_granularity" property of the block device which could
be used by management layer.
Though, in particular, from the point of QEMU, there is

On restart, we were scheduling a BH to process queued requests, which
would run before starting up the data plane, leading to those requests
being assigned and started on coroutines on the main context.
This could cause requests to be wrongly processed in parallel from
different threads (the main
Move the code that processes queued requests from
virtio_blk_dma_restart_bh() to its own, non-static, function. This
will allow us to call it from the virtio_blk_data_plane_start() in a
future patch.

Could you post sequence of your series by subject, or export a git branch?
