>
> Add option, mostly for comparison's sake, that allows a deploy orchestrated
> by CombinedBlockCache such that its L1 is LruBlockCache for META blocks but
> DATA blocks are fetched each time (we don't try and cache them, no blockcache
> churn).
> In operation, i can see fscache coming around to cover the fetched DATA
> blocks such that if the DATA blocks fit in fscache, seeks go to zero.
> This setup for sure runs slower. Will publish numbers elsewhere. Meantime,
> here is a patch to enable this option.
