2824 Here is a matrix of mmap possibilities:
2825 mmap private not fixed
2826 mmap private fixed at somewhere currently unmapped
2827 mmap private fixed at somewhere already mapped
2828 mmap shared not fixed
2829 mmap shared fixed at somewhere currently unmapped
2830 mmap shared fixed at somewhere already mapped
2831 For private mappings, we should verify that changes cannot be read()
2832 back from the file, nor mmap's back from the file at a different
2833 address. (There have been systems where private was not correctly
2834 implemented like the infamous i386 svr4.0, and systems where the
2835 VM page cache was not coherent with the filesystem buffer cache
2836 like early versions of FreeBSD and possibly contemporary NetBSD.)
2837 For shared mappings, we should conversely verify that changes get
2838 propogated back to all the places they're supposed to be.
2839
2840 Grep wants private fixed already mapped.
2841 The main things grep needs to know about mmap are:
2842 * does it exist and is it safe to write into the mmap'd area
2843 * how to use it (BSD variants) */
