  32 # DESCRIPTION:
  33 #        Verify file read/write is coherent with mmap.
  34 #
  35 # STRATEGY:
  36 #       1. run "mount -F smbfs //server/public /export/mnt"
  37 #       2. open and mmap a test file
  38 #       3. write something into test file, then check the result through mmap
  39 #       4. memset some parts of mmaped addr, then check the result through
  40 #          file read
  41 #       5. close test file
