* 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 make 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.
