| * The file system is made out of blocks of at most MAXBSIZE units, |
| * with smaller units (fragments) only in the last direct block. |
| * MAXBSIZE primarily determines the size of buffers in the buffer |
| * pool. It may be made larger without any effect on existing |
| * file systems; however making it smaller may make some file |
| * systems unmountable. |
| * |
| * Note that the blocked devices are assumed to have DEV_BSIZE |
| * "sectors" and that fragments must be some multiple of this size. |
