From d43d6aea844e66b847e3a0e5cb2c24b6ba84908a Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 24 Apr 2012 00:25:08 -0400 Subject: [PATCH] target: remove the t_task_cdbs_ex_left field in struct se_cmd Now that tasks are gone we are guaranteed to only get a single completion per command, and thus don't need this counter.
