Since the xattr was just looked up there is a high chance that the TNC will still contain the node. A new inode needs to be allocated, though. Alternatively we could add a iget_locked/drop_nlink/iput sequence to ubifs_tnc_remove_ino(). But that will make unlink() much slower for files that contain xattrs. Thanks, //richard
