There's a PD controller that tries to keep the amount of dirty data at writeback_percent percentage of your cache size.

Workaround is to set writeback_percent to 0 -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
