How to get the section handle of a memory mapped file within the filter driver

Is there any way to get the section handle of a memory mapped file within
the filter driver ? What I want to do is to use ZwOpenSection(), and
ZwUnmapViewOfSection() to remove the mapped file from the cache.

Thanks & Regards,

Yes, you can use ZwCreateSection and ZwMapViewOfSection.
Note that the view will be mapped to user space and not kernel one.
