flashcache-utils 3.1.3+git20150513-1ubuntu1 (powerpc binary) in ubuntu wily

 Flashcache is a write-back block device cache for Linux. Using the Linux
 device mapper (DM) it provides an overlay mapper, to cache chunks of
 data on a high speed caching device like a solid-state drive for fast
 read access.
 .
 Flashcache supports FIFO and LRU cache sets, is configurable and error
 resistant. It comes with a DKMS kernel module and a corresponding user
 land for command and control.
 .
 This package provides user space utilities, required to control the kernel
 module.
