But since the existing parser is already present, what's so hard about that? By having two different callbacks, one with the old signature and one with the new, with exactly one of the callbacks being non-NULL, it should be relatively easy to decide which of the two callbacks to use. > so I leave them in one big patch, I am sorry it is realy hard to review. I still think that the ease of review that would be added by splitting the patch is worth making the effort. Yes, it may be harder for you, but if the end result is that more people are willing to review the patch, then the community as a whole spends less collective time, and the series will be accepted sooner. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
