  Log:
  Update the vnode's access time after an mmap operation on it.
  Before this change a copy operation with cp(1) would not update the
  file access times.
  
  According to the POSIX mmap(2) documentation: the st_atime field
  of the mapped file may be marked for update at any time between the
  mmap() call and the corresponding munmap() call. The initial read
  or write reference to a mapped region shall cause the file's st_atime
  field to be marked for update if it has not already been marked for
  update.
