3115 Here is a matrix of mmap possibilities:
3116 mmap private not fixed
3117 mmap private fixed at somewhere currently unmapped
3118 mmap private fixed at somewhere already mapped
3119 mmap shared not fixed
3120 mmap shared fixed at somewhere currently unmapped
3121 mmap shared fixed at somewhere already mapped
3122 For private mappings, we should verify that changes cannot be read()
3123 back from the file, nor mmap's back from the file at a different
3124 address. (There have been systems where private was not correctly
3125 implemented like the infamous i386 svr4.0, and systems where the
3126 VM page cache was not coherent with the filesystem buffer cache
3127 like early versions of FreeBSD and possibly contemporary NetBSD.)
3128 For shared mappings, we should conversely verify that changes get
3129 propogated back to all the places they're supposed to be.
3130
3131 Grep wants private fixed already mapped.
3132 The main things grep needs to know about mmap are:
3133 * does it exist and is it safe to write into the mmap'd area
3134 * how to use it (BSD variants) */
