MAXPHYS and MAXBSIZE

[Corey Brune]

According to sys/param.h:

MAXPHYS - max raw I/O transfer size

MAXBSIZE -   Filesystems are made out of blocks of at most MAXBSIZE bytes
               per block.  MAXBSIZE may be made larger without effecting
               any existing filesystems as long as it does not exceed MAXPHYS,
               and may be made smaller at the risk of not being able to use
               filesystems which require a block size exceeding MAXBSIZE.
