Subject[ 001/109] target: Add generation of LOGICAL BLOCK ADDRESS OUT OF RANGE
Date
From: Greg KH <gregkh@linuxfoundation.org>

3.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Roland Dreier <roland@purestorage.com>

commit e2397c704429025bc6b331a970f699e52f34283e upstream.

Many SCSI commands are defined to return a CHECK CONDITION / ILLEGAL
REQUEST with ASC set to LOGICAL BLOCK ADDRESS OUT OF RANGE if the
initiator sends a command that accesses a too-big LBA. Add an enum
value and case entries so that target code can return this status.
