The basic requirement is to know accurately how much memory is being used by the module (and ultimately per-pool device) as I can imagine cases where it's using a significant proportion of the system's memory. I doubt kmemcache would be a satisfactory solution for bufio, but there are other ways to meet this requirement, such as exporting this information in /sys. Initally just a global figure for the module, but evenutally reported per-device (with dm-core support and new target callbacks).
