7245 Here is a matrix of mmap possibilities:
7246 mmap private not fixed
7247 mmap private fixed at somewhere currently unmapped
7248 mmap private fixed at somewhere already mapped
7249 mmap shared not fixed
7250 mmap shared fixed at somewhere currently unmapped
7251 mmap shared fixed at somewhere already mapped
7252 For private mappings, we should verify that changes cannot be read()
7253 back from the file, nor mmap's back from the file at a different
7254 address. (There have been systems where private was not correctly
7255 implemented like the infamous i386 svr4.0, and systems where the
7256 VM page cache was not coherent with the file system buffer cache
7257 like early versions of FreeBSD and possibly contemporary NetBSD.)
7258 For shared mappings, we should conversely verify that changes get
7259 propagated back to all the places they're supposed to be.
7260
7261 Grep wants private fixed already mapped.
7262 The main things grep needs to know about mmap are:
7263 * does it exist and is it safe to write into the mmap'd area
7264 * how to use it (BSD variants) */
