6776 Here is a matrix of mmap possibilities:
6777 mmap private not fixed
6778 mmap private fixed at somewhere currently unmapped
6779 mmap private fixed at somewhere already mapped
6780 mmap shared not fixed
6781 mmap shared fixed at somewhere currently unmapped
6782 mmap shared fixed at somewhere already mapped
6783 For private mappings, we should verify that changes cannot be read()
6784 back from the file, nor mmap's back from the file at a different
6785 address. (There have been systems where private was not correctly
6786 implemented like the infamous i386 svr4.0, and systems where the
6787 VM page cache was not coherent with the file system buffer cache
6788 like early versions of FreeBSD and possibly contemporary NetBSD.)
6789 For shared mappings, we should conversely verify that changes get
6790 propagated back to all the places they're supposed to be.
6791
6792 Grep wants private fixed already mapped.
6793 The main things grep needs to know about mmap are:
6794 * does it exist and is it safe to write into the mmap'd area
6795 * how to use it (BSD variants) */
