From 0685230c59b5482e04ab50e7afc51119ceaba651 Mon Sep 17 00:00:00 2001 From: Joe Eykholt Date: Tue, 20 Jul 2010 15:19:53 -0700 Subject: [SCSI] libfc: add discovery-private pointer for LLD For VN_port to VN_port mode, FIP will do discovery and needs a way to find its state from the local port or discovery structure. It seems that any other LLD that implements its own discovery would also need something like this. Replace disc->lport with disc->priv, and use container_of to find the lport. We could use disc->priv for that, but container_of is smaller and faster.
