Next time please coordinate this with the block list and Jens, who actually wrote the patch.
hints segment type ----- ------------ WRITE_LIFE_SHORT CURSEG_COLD_DATA WRITE_LIFE_EXTREME CURSEG_HOT_DATA others CURSEG_WARM_DATA
Normally cold data is data with a long lifetime, and extreme is colder than cold, so there seems to be some mismatch here.
