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.
