From a2e0f79939e09e74698564b88dee709db208e1e2 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Wed, 11 Aug 2010 09:53:11 +0100 Subject: GFS2: Remove i_disksize With the update of the truncate code, ip->i_disksize and inode->i_size are merely copies of each other. This means we can remove ip->i_disksize and use inode->i_size exclusively reducing the size of a GFS2 inode by 8 bytes.
