2695 Here is a matrix of mmap possibilities:
2696 mmap private not fixed
2697 mmap private fixed at somewhere currently unmapped
2698 mmap private fixed at somewhere already mapped
2699 mmap shared not fixed
2700 mmap shared fixed at somewhere currently unmapped
2701 mmap shared fixed at somewhere already mapped
2702 For private mappings, we should verify that changes cannot be read()
2703 back from the file, nor mmap's back from the file at a different
2704 address. (There have been systems where private was not correctly
2705 implemented like the infamous i386 svr4.0, and systems where the
2706 VM page cache was not coherent with the filesystem buffer cache
2707 like early versions of FreeBSD and possibly contemporary NetBSD.)
2708 For shared mappings, we should conversely verify that changes get
2709 propogated back to all the places they're supposed to be.
2710
2711 Grep wants private fixed already mapped.
2712 The main things grep needs to know about mmap are:
2713 * does it exist and is it safe to write into the mmap'd area
2714 * how to use it (BSD variants) */
