    Description

      It would be nice to be able to flush dirty pages from cache without evicting them. Some workloads don't generate a lot of cache pressure, but do want to do checkpoints.

      If the cache is allowed to have a lot of dirty content then checkpoints become more expensive.

      It would be good if code:eviction_dirty_target is set below evicting_target we switched to a mode of only "cleaning" dirty pages, rather than evicting them.
