From 6da41f2a740569440e88539779cb94f169b1f1b6 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Mon, 21 Nov 2011 10:27:17 -0500 Subject: [PATCH] btrfs-progs: make sure btrfs-zero-log writes something The close_ctree code does a check to see if the FS has changed before it does any IO. This forces the commit.
