write-back block device cache for Linux (DKMS version)

 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. Alternatively it can be configured as
 write-through and write-around flash cache, which does not store any
 persitent data in the flash volume, hence purging the cache upon reboot.
 .
 This package provides the DKMS kernel module.
 .
 Warning: Flashcache is known not to work on the i686 (x86_32) architecture and
 possibly others.
