2941 Here is a matrix of mmap possibilities:
2942 mmap private not fixed
2943 mmap private fixed at somewhere currently unmapped
2944 mmap private fixed at somewhere already mapped
2945 mmap shared not fixed
2946 mmap shared fixed at somewhere currently unmapped
2947 mmap shared fixed at somewhere already mapped
2948 For private mappings, we should verify that changes cannot be read()
2949 back from the file, nor mmap's back from the file at a different
2950 address. (There have been systems where private was not correctly
2951 implemented like the infamous i386 svr4.0, and systems where the
2952 VM page cache was not coherent with the filesystem buffer cache
2953 like early versions of FreeBSD and possibly contemporary NetBSD.)
2954 For shared mappings, we should conversely verify that changes get
2955 propogated back to all the places they're supposed to be.
2956
2957 Grep wants private fixed already mapped.
2958 The main things grep needs to know about mmap are:
2959 * does it exist and is it safe to write into the mmap'd area
2960 * how to use it (BSD variants) */
