Message-Id: <1222293680-15451-23-git-send-email-mfasheh@suse.com>
Date: Wed, 24 Sep 2008 15:01:03 -0700
From: Mark Fasheh <mfasheh@...e.com>

Subject: [PATCH 22/39] ocfs2: Prefix the extent tree operations structure.
From: Joel Becker <joel.becker@...cle.com>
The ocfs2_extent_tree_operations structure gains a field prefix on its
members. The ->eo_sanity_check() operation gains a wrapper function for
completeness. All of the extent tree operation wrappers gain a
consistent name (ocfs2_et_*()).
