From d397a445f43c7ae9b35260f236a08d5b5760de3d Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Thu, 22 Aug 2013 14:17:20 -0700 Subject: target: Add Third Party Copy (3PC) bit in INQUIRY response This patch adds the Third Party Copy (3PC) bit to signal support for EXTENDED_COPY within standard inquiry response data. Also add emulate_3pc device attribute in configfs (enabled by default) to allow the exposure of this bit to be disabled, if necessary.
