3036    Here is a matrix of mmap possibilities:
3037         mmap private not fixed
3038         mmap private fixed at somewhere currently unmapped
3039         mmap private fixed at somewhere already mapped
3040         mmap shared not fixed
3041         mmap shared fixed at somewhere currently unmapped
3042         mmap shared fixed at somewhere already mapped
3043    For private mappings, we should verify that changes cannot be read()
3044    back from the file, nor mmap's back from the file at a different
3045    address.  (There have been systems where private was not correctly
3046    implemented like the infamous i386 svr4.0, and systems where the
3047    VM page cache was not coherent with the filesystem buffer cache
3048    like early versions of FreeBSD and possibly contemporary NetBSD.)
3049    For shared mappings, we should conversely verify that changes get
3050    propogated back to all the places they're supposed to be.
3051
3052    Grep wants private fixed already mapped.
3053    The main things grep needs to know about mmap are:
3054    * does it exist and is it safe to write into the mmap'd area
3055    * how to use it (BSD variants)  */
