Subject: target: Fix trailing ASCII space usage in INQUIRY vendor+model
From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
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.
