Description of problem:
Newly introduced cache(pool) support in lvm2 currently allows to cache only a single LV.
This interface might not be the best for a user with a single large rotational drive and small SSD where he would need to create small caches for individual LVs (since the dm-cache support only 1:1 mapping)
However cache-pool may also serve to cache a whole single PV - thus we may hide the complexity from a user (as he would be now forced to 'stack' dm-cache PV on his own) and allow to use a single SSD for all LVs from 1 PV (thus still matching 1:1).
The other method which we may explore is - to combine all LVs into 1 large mapping and use LVs this way - this would allow to map even multiple PVs into a single cache device - but with number of problems to resolve when i.e. LVs are resized.
