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.
