From c1e817d03a7de57a963654c35e6e80af9a5dbff5 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Tue, 22 Jul 2008 22:58:03 +0100 Subject: [PATCH] GFS2: Fix debugfs glock file iterator Due to an incorrect iterator, some glocks were being missed from the glock dumps obtained via debugfs. This patch fixes the problem and ensures that we don't miss any glocks in future.
