From 57dff2676eb68d805883a2204faaa5339ac44e03 Mon Sep 17 00:00:00 2001 From: Sunil Mushran Date: Tue, 16 Dec 2008 15:49:20 -0800 Subject: [PATCH] ocfs2/dlm: Clean up errors in dlm_proxy_ast_handler() Patch cleans printed errors in dlm_proxy_ast_handler(). The errors now includes the node number that sent the (b)ast. Also it reduces the number of endian swaps of the cookie.
