From 4b52dff6d371b9b93bc99f64c32831ea9a8ec3ac Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Tue, 26 Jun 2007 10:06:50 -0400 Subject: Btrfs: Fix super block updates during transaction commit The super block written during commit was not consistent with the state of the trees. This change adds an in-memory copy of the super so that we can make sure to write out consistent data during a commit.
