if qps is known to be empty then this should be WARN_ON(!xa_empty()) -
destroying an xarray that holds allocated memory is never correct - it
will leak the elements

Also, this isn't "for-rc", so it should go to -next. With a dependency
like this the patch waits until linus merges the rc branch and then
-next merges linus's rcX tag to resolve the conflict.
