| 2706 | Here is a matrix of mmap possibilities: |
| 2707 | mmap private not fixed |
| 2708 | mmap private fixed at somewhere currently unmapped |
| 2709 | mmap private fixed at somewhere already mapped |
| 2710 | mmap shared not fixed |
| 2711 | mmap shared fixed at somewhere currently unmapped |
| 2712 | mmap shared fixed at somewhere already mapped |
| 2713 | For private mappings, we should verify that changes cannot be read() |
| 2714 | back from the file, nor mmap's back from the file at a different |
| 2715 | address. (There have been systems where private was not correctly |
| 2716 | implemented like the infamous i386 svr4.0, and systems where the |
| 2717 | VM page cache was not coherent with the filesystem buffer cache |
| 2718 | like early versions of FreeBSD and possibly contemporary NetBSD.) |
| 2719 | For shared mappings, we should conversely verify that changes get |
| 2720 | propogated back to all the places they're supposed to be. |
| 2721 | |
| 2722 | Grep wants private fixed already mapped. |
| 2723 | The main things grep needs to know about mmap are: |

| 2725 | * how to use it (BSD variants) */ |
