The decrement is conditioned on whether the ea_inode is currently on the orphan list. However, the orphan list addition only happens when journaling is enabled. In non-journaled case,r we fail to release the ref count causing an error message like below. "VFS: Busy inodes after unmount of sdb. Self-destruct in 5 seconds. Have a nice day..."
