2830 Here is a matrix of mmap possibilities:
2831 mmap private not fixed
2832 mmap private fixed at somewhere currently unmapped
2833 mmap private fixed at somewhere already mapped
2834 mmap shared not fixed
2835 mmap shared fixed at somewhere currently unmapped
2836 mmap shared fixed at somewhere already mapped
2837 For private mappings, we should verify that changes cannot be read()
2838 back from the file, nor mmap's back from the file at a different
2839 address. (There have been systems where private was not correctly
2840 implemented like the infamous i386 svr4.0, and systems where the
2841 VM page cache was not coherent with the filesystem buffer cache
2842 like early versions of FreeBSD and possibly contemporary NetBSD.)
2843 For shared mappings, we should conversely verify that changes get
2844 propogated back to all the places they're supposed to be.
2845
2846 Grep wants private fixed already mapped.
2847 The main things grep needs to know about mmap are:
2848 * does it exist and is it safe to write into the mmap'd area
2849 * how to use it (BSD variants) */
