The patch at the end of this message converts the SCSI tape driver to support
also descriptor based sense data. Test for deferred sense data have been added
in a couple of places and the EOM tests have been unified. Some tests have been
simplified but the patch is not meant to change the current behavior. The
patch is against 2.6.11-rc4 and has been tested to some extent.

The patch also includes the msleep_interruptible change from from kernel
janitors.

Thanks to Doug Gilbert for doing a first version of this sense data
conversion.
