> The remote-read data cache is a major consumer of physical memory.
> It would be useful to have a "bytes in core" metric for the cache that
> reports the current in core physical size of the Linux page cache memory for
> the data cache. This is useful for tuning data cache size or analyzing the
> impact of the data cache on host memory use and memory pressure.
