%description
DRBD is a distributed replicated block device. It mirrors a
block device over the network to another machine. Think of it
as networked raid 1. It is a building block for setting up
high availability (HA) clusters.
This package provides the %{kmod_name} kernel module(s).
It is built to depend upon the specific ABI provided by a range of releases
of the same variant of the Linux kernel and not on any one specific build.
