Thanks for the test, I actually have a patch for this one, if Christoph and Sagi okay with that I can work on it.
Although, not sure if we want that sort of management code in the target.

Subject: [PATCH blktests 2/2] nvme: test resize of a namespace with file-backed ns
Test resizing of a NVMe namespace by creating a file backed namespace over
nvme-loop with 1G size, connecting to it and then resizing it to 2G.
Check if /proc/partitions and blkdev --getsz $DEVICE see the updated size.
