3.2.51-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Nicholas Bellinger <n...@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.
