Unfortunately the patch wasn't quite correct - all TEST_UNIT_READY
commands are sent as BLOCK_PC, so this would basically revert James'
original fix for the SATL case.
Am I right to assume you only need the call to scsi_dh->check_sense and
not the rest of the handling for the multipath path checker? If that's
the case something like the patch below sould work:
