34 * File system parameters and macros.
35 *
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 may 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.
