From 4a221953ed121692aa25998451a57c7f4be8b4f6 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Wed, 1 Nov 2006 09:57:57 -0500 Subject: [PATCH] [GFS2] Fix incorrect fs sync behaviour. This adds a sync_fs superblock operation for GFS2 and removes the journal flush from write_super in favour of sync_fs where it ought to be. This is more or less identical to the way in which ext3 does this.
