From b43f1886e4d3ea3f68665eaea96526ccdd53741d Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Tue, 17 Jun 2014 22:23:03 +0000 Subject: [PATCH] tcm_loop: Fix memory leak in tcm_loop_submission_work error path This patch fixes a tcm_loop_cmd descriptor memory leak in the tcm_loop_submission_work() error path, and would result in warnings about leaked tcm_loop_cmd_cache objects at module unload time. Go ahead and invoke kmem_cache_free() to release tl_cmd back to tcm_loop_cmd_cache before calling sc->scsi_done().
