From 5de619a31d9cb051d1f818e661af4e54def82316 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Sun, 17 Jul 2011 02:57:58 -0700 Subject: target: Update QUEUE ALGORITHM MODIFIER control page default This patch adds the default 'Unrestricted reordering allowed' for SCSI control mode page QUEUE ALGORITHM MODIFIER on a per se_device basis in target_modesense_control() following spc4r23. This includes a new emuluate_rest_reord configfs attribute that currently (only) accepts zero to signal 'Unrestricted reordering allowed' in control mode page usage by the backend target device.
