6e31fd8306 Relax and cleanup HARDWARE ERROR sense usage 
HARDWARE ERROR sense is very strong considered be "internal failure", so
might lead to serios initiator side issues up to disconnect from device. In
many cases WRITE or READ ERROR sense can be used instead. All remaining
usages must be logged.

606af43444 scst_vdisk: Avoid triggering BUG() for large LBA's 
The LBA field in READ(16) and READ(32) commands is 64 bits wide.
Hence it is possible for an initiator not only to specify an offset
that exceeds 2**63. Report an error to the initiator for such large
offsets instead of triggering a BUG().  This patch fixes the following bug:

Make sure that suspend_count is decremented if scst_suspend_activity()
times out. Also, if a timeout is encountered, clear SCST_FLAG_SUSPENDING
before waking up the command threads instead of after waking up these
threads.

84f6cb5dae scst_vdisk: Add support for nullio "dummy" LUNs 
While the SCSI specifications require presence of LUN 0 it is not always
desirable to associate storage with LUN 0. Hence allow LUN 0 (or any
other LUN) to be configured such that it does not appear at the
initiator side. This is realized by adding a "dummy" attribute in to
NULLIO vdisk devices. If that attribute is set, the PERIPHERAL QUALIFIER
field in the INQUIRY response is set to 1 and the PERIPHERAL DEVICE TYPE
is set to 0x1f. Add an example in the scst.conf(5) man page that shows
how to use the new attribute.
