Also even if the user decided to not use THP, by
echo "never" > transparent_hugepage/enabled , we should continue to map
dax fault using huge page on platforms that can support huge pages.

Is this a good idea?

This knob is there for a reason. In some situations having huge pages
can severely impact performance of the system (due to host-guest
interaction or whatever) and the ability to really turn off all THP
would be important in those cases, right?

Thanks
