+spl-linux for Debian
+
+Using DKMS is the recommended way of installing this kernel
+module, however if you do have the need of building deb/udeb
+packages containing the binary kernel module, here is the way.
+Be careful when proceed with this way, as your attention is 
+required when kernel ABI get changed on target system that this
+module needs to be rebuilt and it needs to replace the originally
+installed package with this newly built one on target system.
+
+You may first install all required build dependency on a machine
+that runs the very same kernel as on your target system, then
+execute following command at the top level directory of the
+decompressed debian source package. Do not install the generated 
+package with kernels that have different configuration, which is
+not supported and likely to break things.
