Not good - I did a diff of fence.h and dma_fence.h, it *appears* to be the same structures, but all with different names. That's not going to compile. Sorry, but I really don't believe it is good, much less best practice to do something like removing a kernel include file within one release. If they'd made it go a away for 7.0, I would deal, but to suddenly drop it, bad. mark
