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,
- key->k_offset, key->k_uniqueness);
