In a DAX mountpoint, do IO betwen files with and without DAX per-inode flag. We do mmap, both O_DIRECT and buffered read/write IO in this case. Then test again in the same device without dax mountoption. Add help _require_scratch_dax to make sure we can test DAX feature on SCRATCH_DEV. Add mmap dio test programme to test read/write between a mmap area of one file and another file directly or buffered, with different size.
