2823 Here is a matrix of mmap possibilities:
2824 mmap private not fixed
2825 mmap private fixed at somewhere currently unmapped
2826 mmap private fixed at somewhere already mapped
2827 mmap shared not fixed
2828 mmap shared fixed at somewhere currently unmapped
2829 mmap shared fixed at somewhere already mapped
2830 For private mappings, we should verify that changes cannot be read()
2831 back from the file, nor mmap's back from the file at a different
2832 address. (There have been systems where private was not correctly
2833 implemented like the infamous i386 svr4.0, and systems where the
2834 VM page cache was not coherent with the filesystem buffer cache
2835 like early versions of FreeBSD and possibly contemporary NetBSD.)
2836 For shared mappings, we should conversely verify that changes get
2837 propogated back to all the places they're supposed to be.
2838
2839 Grep wants private fixed already mapped.
2840 The main things grep needs to know about mmap are:
2841 * does it exist and is it safe to write into the mmap'd area
2842 * how to use it (BSD variants) */
