[svn-r5538] Purpose:
Code improvement.
Description:
Added boot block and driver info block checksumming feature to the shared
file information. This prevents these blocks from being written out
multiple times when they haven't changed.
This reduces the number of I/O operations which hit the disk for my test
program from 15 to 14 (i.e. from 393 to 14, overall).
Platforms tested:
Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
