Hi, @gilbert. I updated the patch a bit differently than you originally requested by creating a `PathValidator` that encapsulate the validation logic instead. Please check if this revision rings a bell to you.

Created a validator class for this purpose instead.

I created a `mesos::internal::slave::volume::PathValidator` helper for this purpose instead.

Done. I created an overloaded constructor that takes a parsed `PathValidator` instance in the case where `_flags.host_path_volume_force_creation` is not `None`.

True. I dropped it in favor of a factory method as part of the `PathValidator` class.
