6763 Here is a matrix of mmap possibilities:
6764 mmap private not fixed
6765 mmap private fixed at somewhere currently unmapped
6766 mmap private fixed at somewhere already mapped
6767 mmap shared not fixed
6768 mmap shared fixed at somewhere currently unmapped
6769 mmap shared fixed at somewhere already mapped
6770 For private mappings, we should verify that changes cannot be read()
6771 back from the file, nor mmap's back from the file at a different
6772 address. (There have been systems where private was not correctly
6773 implemented like the infamous i386 svr4.0, and systems where the
6774 VM page cache was not coherent with the file system buffer cache
6775 like early versions of FreeBSD and possibly contemporary NetBSD.)
6776 For shared mappings, we should conversely verify that changes get
6777 propagated back to all the places they're supposed to be.
6778
6779 Grep wants private fixed already mapped.
6780 The main things grep needs to know about mmap are:
6781 * does it exist and is it safe to write into the mmap'd area
6782 * how to use it (BSD variants) */
