Idea is that kernel allocator already do that for us. I would like to avoid having many pools in the driver, i don't think it's well behaving to do so. And fence are small enough to take advantage of any slab/slub allocator kernel has. However if you have benchmark that shows that fence allocation is slowing down, by huge margin, application than we might consider doing so. But i don't think fence are biggest bottleneck, i am pretty sure memory management is.
