Fair enough.  If you pull from

rsync://www.parisc-linux.org/~jejb/scsi-misc-2.6.git

That will pull in the rest of my scsi-misc-2.6 tree (which includes all
of the rc fixes).  I've done a test pull and merge and checked the
resulting against BK, so hopefully there should be no more screw ups.

Doing this exposed two bugs in your merge script:

1) It doesn't like a completely new directory (the misc tree contains a
new drivers/scsi/lpfc)
2) the merge testing logic is wrong.  You only want to exit 1 if the
merge fails.
