to the last copy from Julian. After this commit I will be commiting the local fixes and makeing diffs to send back to Julian so he can update his code. ---- From julian@jules.DIALix.oz.au Thu Aug 5 09:25:23 1993 To: hd@world.std.com, julian@jules.DIALix.oz.au Cc: nate@bsd.coe.montana.edu Subject: Re: new scsi ---- From julian@jules.DIALix.oz.au Sat Aug 7 04:13:17 1993 To: hd@world.std.com (HD Associates) Cc: nate@bsd.coe.montana.edu Subject: Re: timeout diffs Here are the diffs to take the scsi stuff to my latest tree from what Nate and you received.. the changes remove all the local timeout stuff and use (un)timeout(), ---- From julian@jules.DIALix.oz.au Sat Aug 7 04:13:45 1993 To: hd@world.std.com (HD Associates) Cc: nate@bsd.coe.montana.edu, briggs@csugrad.cs.vt.edu here is a fix for a silly bug in the scsiconf I just sent out and a similar fix for st.c
