From 31fcba00fe7145527b159f8893ec6c9cc61309fd Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Wed, 4 Jun 2008 15:06:21 +0100 Subject: [GFS2] Remove all_list from lock_dlm I discovered that we had a list onto which every lock_dlm lock was being put. Its only function was to discover whether we'd got any locks left after umount. Since there was already a counter for that purpose as well, I removed the list. The saving is sizeof(struct list_head) per glock - well worth having.
