    7457    For private mappings, we should verify that changes cannot be read()
    7458    back from the file, nor mmap's back from the file at a different
    7459    address.  (There have been systems where private was not correctly
    7460    implemented like the infamous i386 svr4.0, and systems where the
    7461    VM page cache was not coherent with the file system buffer cache
    7462    like early versions of FreeBSD and possibly contemporary NetBSD.)
    7463    For shared mappings, we should conversely verify that changes get
    7464    propagated back to all the places they're supposed to be.
    7465 
    7466    Grep wants private fixed already mapped.
    7467    The main things grep needs to know about mmap are:
    7468    * does it exist and is it safe to write into the mmap'd area
    7469    * how to use it (BSD variants)  */
