| 36 | * The file system is made out of blocks of at most MAXBSIZE units, | |
| 37 | * with smaller units (fragments) only in the last direct block. | |
| 38 | * MAXBSIZE primarily determines the size of buffers in the buffer | |
| 39 | * pool. It may be made larger without any effect on existing | |
| 40 | * file systems; however making it smaller make make some file | |
| 41 | * systems unmountable. | |
| 42 | * | |
| 43 | * Note that the blocked devices are assumed to have DEV_BSIZE | |
| 44 | * "sectors" and that fragments must be some multiple of this size. | |
