> This feature is poorly supported, and causes grief for cache development due to how it #ifdef’s with the system. There are plans for a new system that would make the concept of cache hierarchies generic. In the mean time, the suggestion is that if you need this, you use one of
> 	1) Assigning content to volumes and disks via our existing configs.
> 	2) Use Linux’s bcache feature, which comes with Linux 3.10 or later. I suspect e.g. ZFS has something similar.
