2730 Here is a matrix of mmap possibilities:
2731 mmap private not fixed
2732 mmap private fixed at somewhere currently unmapped
2733 mmap private fixed at somewhere already mapped
2734 mmap shared not fixed
2735 mmap shared fixed at somewhere currently unmapped
2736 mmap shared fixed at somewhere already mapped
2737 For private mappings, we should verify that changes cannot be read()
2738 back from the file, nor mmap's back from the file at a different
2739 address. (There have been systems where private was not correctly
2740 implemented like the infamous i386 svr4.0, and systems where the
2741 VM page cache was not coherent with the filesystem buffer cache
2742 like early versions of FreeBSD and possibly contemporary NetBSD.)
2743 For shared mappings, we should conversely verify that changes get
2744 propogated back to all the places they're supposed to be.
2745
2746 Grep wants private fixed already mapped.
2747 The main things grep needs to know about mmap are:
2748 * does it exist and is it safe to write into the mmap'd area
2749 * how to use it (BSD variants) */
