For historical reasons the helpers [btrfs_]open_dir... return also the 'DIR *dirstream' value when a directory is opened. However this is never used. So avoid calling diropen() and return only the fd. This is a preparatory patch. Signed-off-by: Goffredo Baroncelli <kreijack@libero.it> Signed-off-by: David Sterba <dsterba@suse.com>
