2830 | Here is a matrix of mmap possibilities: | |

2833 | mmap private fixed at somewhere already mapped | |
2834 | mmap shared not fixed | |
2835 | mmap shared fixed at somewhere currently unmapped | |
2836 | mmap shared fixed at somewhere already mapped | |
2837 | For private mappings, we should verify that changes cannot be read() | |
2838 | back from the file, nor mmap's back from the file at a different | |
2839 | address. (There have been systems where private was not correctly | |
2840 | implemented like the infamous i386 svr4.0, and systems where the | |
2841 | VM page cache was not coherent with the filesystem buffer cache | |
2842 | like early versions of FreeBSD and possibly contemporary NetBSD.) | |
2843 | For shared mappings, we should conversely verify that changes get | |
2844 | propogated back to all the places they're supposed to be. | |
2845 | ||
2846 | Grep wants private fixed already mapped. | |
