Re: [ntfsd] virtual address to physical address

Sorry, but since you say malloc that implies a user
address that is not tied to any physical address. Also
if the area in question crosses a page boundary the
the pages may be discontinous.

If you are looking for this you need to lock the area
into memory with a kernel call MmProbeAndLockPages
after building a MDL for the area. It is then possible
to get the physical address of the specific pages.

Tell us what you want to do, and maybe there is an
easier way.
