7360 Here is a matrix of mmap possibilities:
7361 mmap private not fixed
7362 mmap private fixed at somewhere currently unmapped
7363 mmap private fixed at somewhere already mapped
7364 mmap shared not fixed
7365 mmap shared fixed at somewhere currently unmapped
7366 mmap shared fixed at somewhere already mapped
7367 For private mappings, we should verify that changes cannot be read()
7368 back from the file, nor mmap's back from the file at a different
7369 address. (There have been systems where private was not correctly
7370 implemented like the infamous i386 svr4.0, and systems where the
7371 VM page cache was not coherent with the file system buffer cache
7372 like early versions of FreeBSD and possibly contemporary NetBSD.)
7373 For shared mappings, we should conversely verify that changes get
7374 propagated back to all the places they're supposed to be.
7375
7376 Grep wants private fixed already mapped.
7377 The main things grep needs to know about mmap are:
7378 * does it exist and is it safe to write into the mmap'd area
7379 * how to use it (BSD variants) */
