You should never have to update any userspace code or library if the kernel is updated as we guarantee backwards compatibility. If we did break something, please let us know and we will work very hard to fix it. This is a guarantee we made back in 2007 or so, and have been sticking to it since. There is no "major" upgrade issue here, the kernel does a new release every 3 months and changes the number, showing it is "newer" than the previous one. Hope this helps, greg k-h
