3104 Here is a matrix of mmap possibilities:
3105 mmap private not fixed
3106 mmap private fixed at somewhere currently unmapped
3107 mmap private fixed at somewhere already mapped
3108 mmap shared not fixed
3109 mmap shared fixed at somewhere currently unmapped
3110 mmap shared fixed at somewhere already mapped
3111 For private mappings, we should verify that changes cannot be read()
3112 back from the file, nor mmap's back from the file at a different
3113 address. (There have been systems where private was not correctly
3114 implemented like the infamous i386 svr4.0, and systems where the
3115 VM page cache was not coherent with the filesystem buffer cache
3116 like early versions of FreeBSD and possibly contemporary NetBSD.)
3117 For shared mappings, we should conversely verify that changes get
3118 propogated back to all the places they're supposed to be.
3119
3120 Grep wants private fixed already mapped.
3121 The main things grep needs to know about mmap are:
3122 * does it exist and is it safe to write into the mmap'd area
3123 * how to use it (BSD variants) */
