2829 Here is a matrix of mmap possibilities:
2830 mmap private not fixed
2831 mmap private fixed at somewhere currently unmapped
2832 mmap private fixed at somewhere already mapped
2833 mmap shared not fixed
2834 mmap shared fixed at somewhere currently unmapped
2835 mmap shared fixed at somewhere already mapped
2836 For private mappings, we should verify that changes cannot be read()
2837 back from the file, nor mmap's back from the file at a different
2838 address. (There have been systems where private was not correctly
2839 implemented like the infamous i386 svr4.0, and systems where the
2840 VM page cache was not coherent with the filesystem buffer cache
2841 like early versions of FreeBSD and possibly contemporary NetBSD.)
2842 For shared mappings, we should conversely verify that changes get
2843 propogated back to all the places they're supposed to be.
2844
2845 Grep wants private fixed already mapped.
2846 The main things grep needs to know about mmap are:
2847 * does it exist and is it safe to write into the mmap'd area
2848 * how to use it (BSD variants) */
