3281 Here is a matrix of mmap possibilities:
3282 mmap private not fixed
3283 mmap private fixed at somewhere currently unmapped
3284 mmap private fixed at somewhere already mapped
3285 mmap shared not fixed
3286 mmap shared fixed at somewhere currently unmapped
3287 mmap shared fixed at somewhere already mapped
3288 For private mappings, we should verify that changes cannot be read()
3289 back from the file, nor mmap's back from the file at a different
3290 address. (There have been systems where private was not correctly
3291 implemented like the infamous i386 svr4.0, and systems where the
3292 VM page cache was not coherent with the filesystem buffer cache
3293 like early versions of FreeBSD and possibly contemporary NetBSD.)
3294 For shared mappings, we should conversely verify that changes get
3295 propogated back to all the places they're supposed to be.
3296
3297 Grep wants private fixed already mapped.
3298 The main things grep needs to know about mmap are:
3299 * does it exist and is it safe to write into the mmap'd area
3300 * how to use it (BSD variants) */
