In 4.1bsd, the raw I/O is done thru physio(). The last parameter is
a routine to determine the maximum count to be transferred. The
routine used is mostly minphys(), which limits it to 60K. So this
means that raw I/O is done thru 60K bytes at most, right? Can this
value be changed without any side affects? We want this for an
application that does fast disk-disk backups (on RM05s).
