From 5a3b6fc0092c5f8dee7820064ee54d2631d48573 Mon Sep 17 00:00:00 2001 From: Roland Dreier <roland@purestorage.com> Date: Wed, 2 Jan 2013 12:47:59 -0800 Subject: [PATCH] target: Release se_cmd when LUN lookup fails for TMR When transport_lookup_tmr_lun() fails and we return a task management response from target_complete_tmr_failure(), we need to call transport_cmd_check_stop_to_fabric() to release the last ref to the cmd after calling se_tfo->queue_tm_rsp(), or else we will never remove the failed TMR from the session command list (and we'll end up waiting forever when trying to tear down the session).
