* File system parameters and macros.

* 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.
