From 110946c8fb23c1e1e23312afed0977ad4aa37c95 Mon Sep 17 00:00:00 2001 From: Joel Becker Date: Fri, 29 Jan 2010 15:46:23 -0800 Subject: ocfs2: Hang the locking proto on the cluster conn and use it in asts. With the ocfs2_cluster_connection hanging off of the ocfs2_dlm_lksb, we have access to it in the ast and bast wrapper functions. Attach the ocfs2_locking_protocol to the conn. Now, instead of refering to a static variable for ast/bast pointers, the wrappers can look at the connection. This means different connections can have different ast/bast pointers, and it reduces the need for the static pointer.
