2317 Here is a matrix of mmap possibilities:
2318 mmap private not fixed
2319 mmap private fixed at somewhere currently unmapped
2320 mmap private fixed at somewhere already mapped
2321 mmap shared not fixed
2322 mmap shared fixed at somewhere currently unmapped
2323 mmap shared fixed at somewhere already mapped
2324 For private mappings, we should verify that changes cannot be read()
2325 back from the file, nor mmap's back from the file at a different
2326 address. (There have been systems where private was not correctly
2327 implemented like the infamous i386 svr4.0, and systems where the
2328 VM page cache was not coherent with the filesystem buffer cache
2329 like early versions of FreeBSD and possibly contemporary NetBSD.)
2330 For shared mappings, we should conversely verify that changes get
2331 propogated back to all the places they're supposed to be.
2332
2333 Grep wants private fixed already mapped.
2334 The main things grep needs to know about mmap are:
2335 * does it exist and is it safe to write into the mmap'd area
2336 * how to use it (BSD variants) */
