From ff8f33c8b30d7b7efdcf2548c7f6e64db6a89b29 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Wed, 11 Aug 2010 09:37:53 +0100 Subject: GFS2: New truncate sequence This updates GFS2's truncate code to use the new truncate sequence correctly. This is a stepping stone to being able to remove ip->i_disksize in favour of using i_size everywhere now that the two sizes are always identical.
