3011 Here is a matrix of mmap possibilities:
3012 mmap private not fixed
3013 mmap private fixed at somewhere currently unmapped
3014 mmap private fixed at somewhere already mapped
3015 mmap shared not fixed
3016 mmap shared fixed at somewhere currently unmapped
3017 mmap shared fixed at somewhere already mapped
3018 For private mappings, we should verify that changes cannot be read()
3019 back from the file, nor mmap's back from the file at a different
3020 address. (There have been systems where private was not correctly
3021 implemented like the infamous i386 svr4.0, and systems where the
3022 VM page cache was not coherent with the filesystem buffer cache
3023 like early versions of FreeBSD and possibly contemporary NetBSD.)
3024 For shared mappings, we should conversely verify that changes get
3025 propogated back to all the places they're supposed to be.
3027 Grep wants private fixed already mapped.
3028 The main things grep needs to know about mmap are:
3029 * does it exist and is it safe to write into the mmap'd area
3030 * how to use it (BSD variants) */
