I didn't publish it yet, but I also made it compile both in userspace and as a kernel module. It's the top two commits here: http://git.infradead.org/users/willy/linux-dax.git/shortlog/refs/heads/xarray-2018-02-12 Note this is a complete rewrite compared to the version presented here; it sits on top of the XArray and no longer has a preload interface. It has a superset of the IDA functionality.
