+ Bcache allows the use of SSDs to cache other block devices.
+ .
+ Documentation for the run-time interface is included in the kernel tree; in
+ Documentation/bcache.txt.
+ .
+ This package includes udev rules, initramfs support, and the utilities to
+ create a new bcache as well as inspect existing bcache partitions.
