Subject[PATCH 07/35] ocfs2: Wrap up the common use cases of ocfs2_new_path().
Date
From: Joel Becker <joel.becker@oracle.com>

The majority of ocfs2_new_path() calls are:

ocfs2_new_path(path_root_bh(otherpath),
path_root_el(otherpath));

Let's call that ocfs2_new_path_from_path(). The rest do similar things
from struct ocfs2_extent_tree. Let's call those
ocfs2_new_path_from_et(). This will make the next change easier.
