/proc/self/mountinfo doesn't exist on older Linux kernels. What is
upstream GRUB's minimum required version of Linux kernel?

Any of 2.x or 3.x line should work. However on older ones we just scan /dev to find a device with the same major/minor as the one we've got from stat (). It's possible to try to use mtab or /proc/mounts as hint while still checking for major/minor match but it's not important. Also I don't suppose anyone will use ZFS with older kernels
