2997 Here is a matrix of mmap possibilities:
2998 mmap private not fixed
2999 mmap private fixed at somewhere currently unmapped
3000 mmap private fixed at somewhere already mapped
3001 mmap shared not fixed
3002 mmap shared fixed at somewhere currently unmapped
3003 mmap shared fixed at somewhere already mapped
3004 For private mappings, we should verify that changes cannot be read()
3005 back from the file, nor mmap's back from the file at a different
3006 address. (There have been systems where private was not correctly
3007 implemented like the infamous i386 svr4.0, and systems where the
3008 VM page cache was not coherent with the filesystem buffer cache
3009 like early versions of FreeBSD and possibly contemporary NetBSD.)
3010 For shared mappings, we should conversely verify that changes get
3011 propogated back to all the places they're supposed to be.
3013 Grep wants private fixed already mapped.
3014 The main things grep needs to know about mmap are:
3015 * does it exist and is it safe to write into the mmap'd area
3016 * how to use it (BSD variants) */
