This might generate additional work e.g. for downstreams (we at SUSE have scripts checking "Fixes:" tags and require such changes to be applied to kernels having the fixed patch applied). That said I'd prefer not having a "Fixes:" tag for such changes, but maybe this is just due to the fact that it would be me having to apply this patch to the SUSE kernels... Juergen
