This is the third version of the SCSI driver to support the adapter implemented by the IBM Power5 firmware. I have incorporated all comments from the previous submissions. Probably the most significant functional change is that all locking is done with the host_lock now. If anyone would prefer to review the code in a prettier c2html format, you can see it at http://www-users.cs.umn.edu/~boutcher/ibmvscsi/ And there is a tarball at ftp://ftp.cs.umn.edu/dept/users/boutcher/ibmvscsi-feb22b.tar.gz Thanks, Dave Boutcher
