But since you’re looking into this part now, would it make sense to do the check in the block layer only if the driver imposes a power of two? We can also do it down the road, but seems like double work. The whole block layer chunk / zone handling has always assumed power of two zone sizes. Changing that would introduce expensive divisions in the fast path. This patch just moves the check to where it belongs.
