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