From 02928a71ae6da6e3e205d99e1fa1a1f598ddb62d Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Fri, 6 Oct 2006 18:51:46 -0700 Subject: [PATCH] ocfs2: remove unused ocfs2_handle_add_inode() We can also delete the unused infrastructure which was once in place to support this functionality. ocfs2_inode_private loses ip_handle and ip_handle_list. ocfs2_journal_handle loses handle_list.
