When using mmap() for file i/o, writing to the file should update it's c/mtime. Specifically if we first mmap-read from a page, then memap-write to the same page. This test was failing for the initial submission of DAX because pfn based mapping do not have an page_mkwrite called for them. The new Kernel patches that introduce pfn_mkwrite fixes this test. Test adapted from a script originally written by Dave Chinner.
