Subject: [patch 0/3] Fixup rb_root initializations to use RB_ROOT

Eric Paris found a problem with rb_root initializations and sent a patch to
fix it here:
http://lkml.indiana.edu/hypermail/linux/kernel/1002.2/02946.html
btrfs: use RB_ROOT to intialize rb_trees instead of setting rb_node to NULL

Based on that, a simple grep for "rb_node = NULL" showed few more similar
usages in ext3, ext4 and jffs2. Here are the patches to fix those
root.rb_node = NULL
usages to
root = RB_ROOT

Compile tested.
