2661 Here is a matrix of mmap possibilities:
2662 mmap private not fixed
2663 mmap private fixed at somewhere currently unmapped
2664 mmap private fixed at somewhere already mapped
2665 mmap shared not fixed
2666 mmap shared fixed at somewhere currently unmapped
2667 mmap shared fixed at somewhere already mapped
2668 For private mappings, we should verify that changes cannot be read()
2669 back from the file, nor mmap's back from the file at a different
2670 address. (There have been systems where private was not correctly
2671 implemented like the infamous i386 svr4.0, and systems where the
2672 VM page cache was not coherent with the filesystem buffer cache
2673 like early versions of FreeBSD and possibly contemporary NetBSD.)
2674 For shared mappings, we should conversely verify that changes get
2675 propogated back to all the places they're supposed to be.
2676
2677 Grep wants private fixed already mapped.
2678 The main things grep needs to know about mmap are:
2679 * does it exist and is it safe to write into the mmap'd area
2680 * how to use it (BSD variants) */
