Hello.

Attached is a small test-case that
demonstrates the problem.
The problem happens if you change
some data in a file-backed private
mapping and then use mremap on
it with MREMAP_DONTUNMAP flag.
The result is:
- destination copy is valid
- source copy restored from the original file

So the 2 copies do not match.
