I've added a patchset (https://review.spdk.io/gerrit/c/spdk/spdk/+/5301) that gives an indication of the changes that would be required for an initial cut at adding Windows support to SPDK. These are just an indication of what some of the changes might look like.  It is still very much WIP, so please don't focus too much on the details - it's just intended as a courtesy 'heads up'. If anyone would like to play with the code, the repo at https://github.com/wpdk/wpdk contains build instructions and further details on the current state. Regards, Nick
