From c01706982350224a6c3653ca5b6f24f37dbbecad Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Tue, 31 Oct 2017 11:03:11 -0700 Subject: target: Inline transport_put_cmd() Since all transput_put_cmd() does is to call target_put_sess_cmd(), inline transport_put_cmd() into its callers. Leave out the BUG_ON() statement because if cmd->se_tfo == NULL then cmd->cmd_kref is 0 and kref_put() will complain anyway. Notes: - transport_init_se_cmd() initializes both .se_tfo and .cmd_kref. - The only target driver that does not call transport_init_se_cmd() for all commands is the iSCSI target driver. See also iscsi_target_rx_opcode().
