From 2650d71e244fb3637b5f58a0080682a8bf9c7091 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 1 May 2015 17:47:58 +0200 Subject: target: move transport ID handling to the core Now that struct se_portal_group contains a protocol identifier field we can take all the code to format an parse protocol identifiers in CDBs into common code instead of leaving this to low-level drivers.
