From 9c58b7ddd70dd7bfaac4ca87131f36d10aaba441 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Wed, 15 Aug 2012 14:35:25 -0700 Subject: target: Simplify fabric sense data length handling Every fabric driver has to supply a se_tfo->set_fabric_sense_len() method, just so iSCSI can return an offset of 2. However, every fabric driver is already allocating a sense buffer and passing it into the target core, either via transport_init_se_cmd() or target_submit_cmd(). So instead of having iSCSI pass the start of its sense buffer into the core and then later tell the core to skip the first 2 bytes, it seems easier for iSCSI just to do the offset of 2 when it passes the sense buffer into the core. Then we can drop the se_tfo->set_fabric_sense_len() everywhere, and just add a couple of lines of code to iSCSI to set the sense data length to the beginning of the buffer right before it sends it over the network. (nab: Remove .set_fabric_sense_len usage from tcm_qla2xxx_npiv_ops + change transport_get_sense_buffer to follow v3.6-rc6 code w/o ->set_fabric_sense_len usage) Signed-off-by: Roland Dreier Signed-off-by: Nicholas Bellinger --- drivers/vhost/tcm_vhost.c | 7 ------- 1 file changed, 7 deletions(-) (limited to 'drivers/vhost') diff --git a/drivers/vhost/tcm_vhost.c b/drivers/vhost/tcm_vhost.c index 94e6e04aecf2..89dc99baca80 100644 --- a/drivers/vhost/tcm_vhost.c +++ b/drivers/vhost/tcm_vhost.c @@ -330,12 +330,6 @@ static int tcm_vhost_queue_tm_rsp(struct se_cmd *se_cmd) return 0; } -static u16 tcm_vhost_set_fabric_sense_len(struct se_cmd *se_cmd, - u32 sense_length) -{ - return 0; -} - static void vhost_scsi_free_cmd(struct tcm_vhost_cmd *tv_cmd) { struct se_cmd *se_cmd = &tv_cmd->tvc_se_cmd; @@ -1526,7 +1520,6 @@ static struct target_core_fabric_ops tcm_vhost_ops = { .queue_data_in = tcm_vhost_queue_data_in, .queue_status = tcm_vhost_queue_status, .queue_tm_rsp = tcm_vhost_queue_tm_rsp, - .set_fabric_sense_len = tcm_vhost_set_fabric_sense_len, /* * Setup callers for generic logic in target_core_fabric_configfs.c */ -- cgit v1.2.3
