2706 Here is a matrix of mmap possibilities:
2707 mmap private not fixed
2708 mmap private fixed at somewhere currently unmapped
2709 mmap private fixed at somewhere already mapped
2710 mmap shared not fixed
2711 mmap shared fixed at somewhere currently unmapped
2712 mmap shared fixed at somewhere already mapped
2713 For private mappings, we should verify that changes cannot be read()
2714 back from the file, nor mmap's back from the file at a different
2715 address. (There have been systems where private was not correctly
2716 implemented like the infamous i386 svr4.0, and systems where the
2717 VM page cache was not coherent with the filesystem buffer cache
2718 like early versions of FreeBSD and possibly contemporary NetBSD.)
2719 For shared mappings, we should conversely verify that changes get
2720 propogated back to all the places they're supposed to be.
2721
2722 Grep wants private fixed already mapped.
2723 The main things grep needs to know about mmap are:
2724 * does it exist and is it safe to write into the mmap'd area
2725 * how to use it (BSD variants) */
