2928 Here is a matrix of mmap possibilities:
2929 mmap private not fixed
2930 mmap private fixed at somewhere currently unmapped
2931 mmap private fixed at somewhere already mapped
2932 mmap shared not fixed
2933 mmap shared fixed at somewhere currently unmapped
2934 mmap shared fixed at somewhere already mapped
2935 For private mappings, we should verify that changes cannot be read()
2936 back from the file, nor mmap's back from the file at a different
2937 address. (There have been systems where private was not correctly
2938 implemented like the infamous i386 svr4.0, and systems where the
2939 VM page cache was not coherent with the filesystem buffer cache
2940 like early versions of FreeBSD and possibly contemporary NetBSD.)
2941 For shared mappings, we should conversely verify that changes get
2942 propogated back to all the places they're supposed to be.
2944 Grep wants private fixed already mapped.
2945 The main things grep needs to know about mmap are:
2946 * does it exist and is it safe to write into the mmap'd area
2947 * how to use it (BSD variants) */
