In kvm I don't add compatibility #ifdefs to mainline, instead I have an awk script that massages the sources into something that all kernels can grok. It isn't pretty but it works. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
