Hi Folks, While there are some good references for block drivers such as loop and null_blk, I've not see a good bare bones block multiqueue example driver. This may not mean that one doesn't exist but since I personally have not seen one, I've created one called blk_example which I've posted on my github account: https://github.com/cdupuis1/nvme_test/tree/master/blk_example. I've tried to make as bare bones a driver that actually still will work as a small block device, /dev/blk_example. The memory footprint of the backing store is relatively small, 2000 sectors or 1MB, but is resizeable with the num_sectors module parameter. It was helpful as a learning experience for me so I'd thought I would share in case anyone else happened to be looking for such a sample driver. Comments or improvements are welcome.
