From 123521830c0ea35055b900d2ff0b73bb129e08cb Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Fri, 27 May 2011 11:16:33 +0000 Subject: iscsi: Resolve iscsi_proto.h naming conflicts with drivers/target/iscsi This patch renames the following iscsi_proto.h structures to avoid namespace issues with drivers/target/iscsi/iscsi_target_core.h: *) struct iscsi_cmd -> struct iscsi_scsi_req *) struct iscsi_cmd_rsp -> struct iscsi_scsi_rsp *) struct iscsi_login -> struct iscsi_login_req This patch includes useful ISCSI_FLAG_LOGIN_[CURRENT,NEXT]_STAGE*, and ISCSI_FLAG_SNACK_TYPE_* definitions used by iscsi_target_mod, and fixes the incorrect definition of struct iscsi_snack to following RFC-3720 Section 10.16. SNACK Request. Also, this patch updates libiscsi, iSER, be2iscsi, and bn2xi to use the updated structure definitions in a handful of locations. Signed-off-by: Mike Christie Signed-off-by: Nicholas A.
