1. A method comprising:

  • directly mapping a logical address of a backing store to a logical address of a non-volatile cache;

    mapping, in a logical-to-physical mapping structure, the logical address of the non-volatile cache to a physical location in the non-volatile cache, the physical location storing data associated with the logical address of the backing store; and

    removing the mapping to the physical location from the logical-to-physical mapping structure in response to evicting the data from the non-volatile cache such that membership in the logical-to-physical mapping structure denotes storage in the non-volatile cache.
