4022/* Thanks to Mike Haertel and Jim Avera for this test.
4023 Here is a matrix of mmap possibilities:
4024 mmap private not fixed
4025 mmap private fixed at somewhere currently unmapped
4026 mmap private fixed at somewhere already mapped
4027 mmap shared not fixed
4028 mmap shared fixed at somewhere currently unmapped
4029 mmap shared fixed at somewhere already mapped
4030 For private mappings, we should verify that changes cannot be read()
4031 back from the file, nor mmap's back from the file at a different
4032 address. (There have been systems where private was not correctly
4033 implemented like the infamous i386 svr4.0, and systems where the
4034 VM page cache was not coherent with the filesystem buffer cache
4035 like early versions of FreeBSD and possibly contemporary NetBSD.)
4036 For shared mappings, we should conversely verify that changes get
4037 propogated back to all the places they're supposed to be.
4038
4039 Grep wants private fixed already mapped.
4040 The main things grep needs to know about mmap are:
4041 * does it exist and is it safe to write into the mmap'd area
4042 * how to use it (BSD variants) */
