This is a note to let you know that I have just added a patch titled target: Set CMD_T_ACTIVE bit for Task Management Requests to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 24d59cc503ec8243e5fccfdaea79a34c709b80f7 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger <nab@linux-iscsi.org> Date: Mon, 9 Jun 2014 23:13:20 +0000 Subject: target: Set CMD_T_ACTIVE bit for Task Management Requests commit f15e9cd910c4d9da7de43f2181f362082fc45f0f upstream. This patch fixes a bug where se_cmd descriptors associated with a Task Management Request (TMR) where not setting CMD_T_ACTIVE before being dispatched into target_tmr_work() process context. This is required in order for transport_generic_free_cmd() -> transport_wait_for_tasks() to wait on se_cmd->t_transport_stop_comp if a session reset event occurs while an ABORT_TASK is outstanding waiting for another I/O to complete.
