From 2a745b14bc99d52c29d0c886a110321f651cf183 Mon Sep 17 00:00:00 2001 From: Arne Jansen Date: Wed, 13 Feb 2013 04:20:01 -0700 Subject: [PATCH] Btrfs: fix crash in log replay with qgroups enabled When replaying a log tree with qgroups enabled, tree_mod_log_rewind does a sanity-check of the number of items against the maximum possible number. It calculates that number with the nodesize of fs_root. Unfortunately fs_root is not yet set at this stage. So instead use the nodesize from tree_root, which is already initialized.
