2719 Here is a matrix of mmap possibilities:
2720 mmap private not fixed
2721 mmap private fixed at somewhere currently unmapped
2722 mmap private fixed at somewhere already mapped
2723 mmap shared not fixed
2724 mmap shared fixed at somewhere currently unmapped
2725 mmap shared fixed at somewhere already mapped
2726 For private mappings, we should verify that changes cannot be read()
2727 back from the file, nor mmap's back from the file at a different
2728 address. (There have been systems where private was not correctly
2729 implemented like the infamous i386 svr4.0, and systems where the
2730 VM page cache was not coherent with the filesystem buffer cache
2731 like early versions of FreeBSD and possibly contemporary NetBSD.)
2732 For shared mappings, we should conversely verify that changes get
2733 propogated back to all the places they're supposed to be.
2734
2735 Grep wants private fixed already mapped.
2736 The main things grep needs to know about mmap are:
2737 * does it exist and is it safe to write into the mmap'd area
2738 * how to use it (BSD variants) */
