[PATCH 22/39] ocfs2: Prefix the extent tree operations structure.

Mark Fasheh
2008-09-24T22:07:34Z

From: Joel Becker <joel.becker@oracle.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_*()).
