From 89a55897a2fbbceb94480952784004bf23911d38 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 14 Oct 2010 14:52:27 -0400 Subject: Btrfs: fix df regression The new ENOSPC stuff breaks out the raid types which breaks the way we were reporting df to the system. This fixes it back so that Available is the total space available to data and used is the actual bytes used by the filesystem. This means that Available is Total - data used - all of the metadata space.
