From a8526e84ac758ac6da45cf273aa1538a6a7aa3de Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 25 Aug 2009 22:36:05 -0400 Subject: ext4: Add missing unlock_new_inode() call in extent migration code We need to unlock the new inode before iput. This patch fixes the following warning when calling chattr +e to migrate a file to use extents. It also fixes problems in when e4defrag attempts to defragment an inode.
