+Subject: target: Fix trailing ASCII space usage in INQUIRY vendor+model
+
+From: Nicholas Bellinger <nab@linux-iscsi.org>
+
+commit ee60bddba5a5f23e39598195d944aa0eb2d455e5 upstream.
+
+This patch fixes spc_emulate_inquiry_std() to add trailing ASCII
+spaces for INQUIRY vendor + model fields following SPC-4 text:
+
+ "ASCII data fields described as being left-aligned shall have any
+ unused bytes at the end of the field (i.e., highest offset) and
+ the unused bytes shall be filled with ASCII space characters (20h)."
+
+This addresses a problem with Falconstor NSS multipathing.
