3279 Here is a matrix of mmap possibilities:
3280 mmap private not fixed
3281 mmap private fixed at somewhere currently unmapped
3282 mmap private fixed at somewhere already mapped
3283 mmap shared not fixed
3284 mmap shared fixed at somewhere currently unmapped
3285 mmap shared fixed at somewhere already mapped
3286 For private mappings, we should verify that changes cannot be read()
3287 back from the file, nor mmap's back from the file at a different
3288 address. (There have been systems where private was not correctly
3289 implemented like the infamous i386 svr4.0, and systems where the
3290 VM page cache was not coherent with the filesystem buffer cache
3291 like early versions of FreeBSD and possibly contemporary NetBSD.)
3292 For shared mappings, we should conversely verify that changes get
3293 propogated back to all the places they're supposed to be.
3294
3295 Grep wants private fixed already mapped.
3296 The main things grep needs to know about mmap are:
3297 * does it exist and is it safe to write into the mmap'd area
3298 * how to use it (BSD variants) */
