    appropriative printk. With this reiserfs_warning you can use format
    specification for complex structures like you used to do with
    printfs for integers, doubles and pointers. For instance, to print
-   out key structure you have to write just: 
-   reiserfs_warning ("bad key %k", key); 
-   instead of 
-   printk ("bad key %lu %lu %lu %lu", key->k_dir_id, key->k_objectid,
