If you want to have a module that can be compiled out of tree and support multiple kernel versions, there is a script used in the v4l-dvb out of tree build system that can make it easier.
http://linuxtv.org/hg/v4l-dvb/raw-file/4ae65d0844cf/v4l/scripts/gentree.pl
This script will process #if/#ifdef/#elif/etc. directives and remove them from the source. It is smart enough to understand LINUX_KERNEL_VERSION tests, && ||, constants, complex expression, etc. It also knows when the result of an expression isn't known and will leave it in the code in that case. We use it to strip the compat code from the source when it's sent to the kernel. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
