	As I pointed out there, ocfs2_num_free_extents() doesn't need
the check - the inode is safe coming in.  I suspect remove_right_path is
the same, though I didn't audit it as much.

	I purposely moved the ocfs2_insert_extent() check to the
_insert_check() helper function because ocfs2_*_insert_extent() go away
in patch 10.
	Check that out, and then let's discuss where sanity/remove_check
is needed.  Maybe we can remove it, or maybe we need to expand its
scope.
