In linux kernel since version 3 (release Date: 2011-07-21)
The block-device backend driver allows the kernel to export its
block devices to other guests via a high-performance shared-memory
interface.
The corresponding Linux frontend driver is enabled by the
CONFIG_XEN_BLKDEV_FRONTEND configuration option.
The backend driver attaches itself to a any block device specified
in the XenBus configuration. There are no limits to what the block
device as long as it has a major and minor.
If you are compiling a kernel to run in a Xen block backend driver
domain (often this is domain 0) you should say Y here. To
compile this driver as a module, chose M here: the module
will be called xen-blkback.
